    Details:

    Parameters:
        peer (:obj:`InputPeer <pyrogram.raw.base.InputPeer>`):

        msg_id (``int`` ``32-bit``):

        big (``bool``, *optional*):
            Whether a bigger and longer reaction should be shown

        add_to_recent (``bool``, *optional*):
            Whether to add this reaction to the `recent reactions list » <https://core.telegram.org/api/reactions#recent-reactions>`_.

        reaction (List of :obj:`Reaction <pyrogram.raw.base.Reaction>`, *optional*):
            A list of reactions (doesn't accept `reactionPaid <https://core.telegram.org/constructor/reactionPaid>`_ constructors, use `messages.sendPaidReaction <https://core.telegram.org/method/messages.sendPaidReaction>`_ to send paid reactions, instead).
