Iterator over the participants belonging to the specified chat.
The order is unspecified.
Arguments
entity (`entity`):
The entity from which to retrieve the participants list.
limit (`int`):
Limits amount of participants fetched.
search (`str`, optional):
Look for participants with this string in name/username.
If ``aggressive is True``, the symbols from this string will
be used.
filter (:tl:`ChannelParticipantsFilter`, optional):
The filter to be used, if you want e.g. only admins
Note that you might not have permissions for some filter.
This has no effect for normal chats or users.
.. note::
The filter :tl:`ChannelParticipantsBanned` will return
*restricted* users. If you want *banned* users you should
use :tl:`ChannelParticipantsKicked` instead.
aggressive (`bool`, optional):
Aggressively looks for all participants in the chat.
This is useful for channels since 20 July 2018,
Telegram added a server-side limit where only the
first 200 members can be retrieved. With this flag
set, more than 200 will be often be retrieved.
This has no effect if a ``filter`` is given.
Yields
The :tl:`User` objects returned by :tl:`GetParticipantsRequest`
with an additional ``.participant`` attribute which is the
matched :tl:`ChannelParticipant` type for channels/megagroups
or :tl:`ChatParticipants` for normal chats.

All the events with a higher (newer) ID or equal to this will
be excluded.
min_id (`int`):
All the events with a lower (older) ID or equal to this will
be excluded.
search (`str`):
The string to be used as a search query.
admins (`entity` | `list`):

invite (`bool`):

link will be returned.
restrict (`bool`):
If `True`, events with partial restrictions will be

If `True`, events removing restrictions will be returned.
This is what the API calls "unban".
ban (`bool`):
If `True`, events applying or removing all restrictions will

all permissions removed is a ban, which kicks the user).
unban (`bool`):
If `True`, events removing all restrictions will be
returned. This is what the API calls "unkick".
promote (`bool`):
If `True`, events with admin promotions will be returned.
demote (`bool`):
If `True`, events with admin demotions will be returned.
info (`bool`):
If `True`, events changing the group info will be returned.

Returns a context-manager object to represent a "chat action".
Chat actions indicate things like "user is typing", "user is
uploading a photo", etc.
If the action is ``'cancel'``, you should just ``await`` the result,
since it makes no sense to use a context-manager for it.
See the example below for intended usage.
Arguments
entity (`entity`):
The entity where the action should be showed in.
action (`str` | :tl:`SendMessageAction`):
The action to show. You can either pass a instance of
:tl:`SendMessageAction` or better, a string used while:
* ``'typing'``: typing a text message.
* ``'contact'``: choosing a contact.
* ``'game'``: playing a game.
* ``'location'``: choosing a geo location.
* ``'record-audio'``: recording a voice note.
You may use ``'record-voice'`` as alias.
* ``'record-round'``: recording a round video.
* ``'record-video'``: recording a normal video.
* ``'audio'``: sending an audio file (voice note or song).
You may use ``'voice'`` and ``'song'`` as aliases.
* ``'round'``: uploading a round video.
* ``'video'``: uploading a video file.
* ``'photo'``: uploading a photo.
* ``'document'``: uploading a document file.
You may use ``'file'`` as alias.
* ``'cancel'``: cancel any pending action in this chat.
Invalid strings will raise a ``ValueError``.
delay (`int` | `float`):
The delay, in seconds, to wait between sending actions.
For example, if the delay is 5 and it takes 7 seconds to
do something, three requests will be made at 0s, 5s, and
7s to cancel the action.
auto_cancel (`bool`):
Whether the action should be cancelled once the context
manager exists or not. The default is `True`, since
you don't want progress to be shown when it has already
completed.
Returns
Either a context-manager object or a coroutine.

Edits admin permissions for someone in a chat.
Raises an error if a wrong combination of rights are given

Arguments

is_admin (`bool`, optional):

This will only work in small group chats.
Whether the user will be an admin in the chat. This is the
only permission available in small group chats, and when
used in megagroups, all non-explicitly set permissions will
have this value.
Essentially, only passing ``is_admin=True`` will grant all
permissions, but you can still disable those you need.
title (`str`, optional):
The custom title (also known as "rank") to show for this admin.

badge will be shown.

"""
Edits user restrictions in a chat.
Set an argument to `False` to apply a restriction (i.e. remove
the permission), or omit them to use the default `True` (i.e.
don't apply a restriction).
Raises an error if a wrong combination of rights are given
(e.g. you don't have enough permissions to revoke one).
By default, each boolean argument is `True`, meaning that it
is true that the user has access to the default permission
and may be able to make use of it.
If you set an argument to `False`, then a restriction is applied
regardless of the default permissions.
It is important to note that `True` does *not* mean grant, only
"don't restrict", and this is where the default permissions come
in. A user may have not been revoked the ``pin_messages`` permission
(it is `True`) but they won't be able to use it if the default
permissions don't allow it either.
Arguments
entity (`entity`):
The channel or megagroup where the restriction should happen.
user (`entity`, optional):
If specified, the permission will be changed for the specific user.
If left as `None`, the default chat permissions will be updated.
until_date (`DateLike`, optional):
When the user will be unbanned.
If the due date or duration is longer than 366 days or shorter than
30 seconds, the ban will be forever. Defaults to ``0`` (ban forever).
view_messages (`bool`, optional):
Whether the user is able to view messages or not.
Forbidding someone from viewing messages equals to banning them.
This will only work if ``user`` is set.
send_messages (`bool`, optional):
Whether the user is able to send messages or not.
send_media (`bool`, optional):
Whether the user is able to send media or not.
send_stickers (`bool`, optional):
Whether the user is able to send stickers or not.
send_gifs (`bool`, optional):
Whether the user is able to send animated gifs or not.
send_games (`bool`, optional):
Whether the user is able to send games or not.
send_inline (`bool`, optional):
Whether the user is able to use inline bots or not.
embed_link_previews (`bool`, optional):
Whether the user is able to enable the link preview in the
messages they send. Note that the user will still be able to
send messages with links if this permission is removed, but
these links won't display a link preview.
send_polls (`bool`, optional):
Whether the user is able to send polls or not.
change_info (`bool`, optional):
Whether the user is able to change info or not.
invite_users (`bool`, optional):
Whether the user is able to invite other users or not.
pin_messages (`bool`, optional):
Whether the user is able to pin messages or not.
Returns
The resulting :tl:`Updates` object.
