This object represents one button of the reply keyboard. For simple text buttons, :obj:`str`
can be used instead of this object to specify text of the button.
Objects of this class are comparable in terms of equality. Two objects of this class are
considered equal, if their :attr:`text`, :attr:`request_contact`, :attr:`request_location`,
:attr:`request_poll`, :attr:`web_app`, :attr:`request_user` and :attr:`request_chat` are equal.
Note:
* Optional fields are mutually exclusive.
* :attr:`request_contact` and :attr:`request_location` options will only work in Telegram
versions released after 9 April, 2016. Older clients will display unsupported message.
* :attr:`request_poll` option will only work in Telegram versions released after 23
January, 2020. Older clients will display unsupported message.
* :attr:`web_app` option will only work in Telegram versions released after 16 April, 2022.
Older clients will display unsupported message.
* :attr:`request_user` and :attr:`request_chat` options will only work in Telegram
versions released after 3 February, 2023. Older clients will display unsupported
message.
