Clicks the inline keyboard button of the message, if any.

Clicks the i'th button (starting from the index 0).
Will ``raise IndexError`` if out of bounds. Example:

>>> # Clicking the 3rd button
>>> # [button1] [button2]
>>> # [ button3 ]
>>> # [button4] [button5]
>>> message.click(2) # index
j (`int`):
Clicks the button at position (i, j), these being the
indices for the (row, column) respectively. Example:
>>> # Clicking the 2nd button on the 1st row.
>>> # [button1] [button2]
>>> # [ button3 ]
>>> # [button4] [button5]
>>> message.click(0, 1) # (row, column)
This is equivalent to ``message.buttons[0][1].click()``.
text (`str` | `callable`):
Clicks the first button with the text "text". This may
also be a callable, like a ``re.compile(...).match``,
and the text will be passed to it.
filter (`callable`):
Clicks the first button for which the callable
returns ``True``. The callable should accept a single
`telethon.tl.custom.messagebutton.MessageButton` argument.
