class SetChatAvailableReactions(TLObject):  # type: ignore
    """Change the set of `message reactions » <https://core.telegram.org/api/reactions>`_ that can be used in a certain group, supergroup or channel

    .. include:: /_includes/usable-by/users.rst

    Details:
        - Layer: ``229``
        - ID: ``864B2581``

    Parameters:
        peer (:obj:`InputPeer <pyrogram.raw.base.InputPeer>`):
            Group where to apply changes

        available_reactions (:obj:`ChatReactions <pyrogram.raw.base.ChatReactions>`):
            Allowed reaction emojis

        reactions_limit (``int`` ``32-bit``, *optional*):
            This flag may be used to impose a custom limit of unique reactions (i.e. a customizable version of `appConfig.reactions_uniq_max <https://core.telegram.org/api/config#reactions-uniq-max>`_ ); this field and the other info set by the method will then be available to users in `channelFull <https://core.telegram.org/constructor/channelFull>`_ and `chatFull <https://core.telegram.org/constructor/chatFull>`_. If this flag is not set, the previously configured ``reactions_limit`` will not be altered.

        paid_enabled (``bool``, *optional*):
            If this flag is set and a `Bool <https://core.telegram.org/type/Bool>`_ is passed, the method will enable or disable `paid message reactions » <https://core.telegram.org/api/reactions#paid-reactions>`_. If this flag is not set, the previously stored setting will not be changed.

    Returns:
        :obj:`Updates <pyrogram.raw.base.Updates>`
