        """Use this method to send reactions on a message/stories.
        Automatically forwarded messages from a channel to its discussion group have the same available reactions as messages in the channel.
        Bots can't use paid reactions.
        
        You must use exactly one of ``message_id`` OR ``story_id``.
        
            If you specify, ``message_id``
                .. include:: /_includes/usable-by/users-bots.rst
                
            If you specify, ``story_id``
                .. include:: /_includes/usable-by/users.rst

        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.
                You can also use chat public link in form of *t.me/<username>* (str).

            message_id (``int``, *optional*):
                Identifier of the target message. If the message belongs to a media group, the reaction is set to the first non-deleted message in the group instead.

            story_id (``int``, *optional*):
                Identifier of the story.

            emoji (``int`` | ``str`` | List of ``int`` | ``str``, *optional*):
                Reaction emoji.
                Pass None as emoji (default) to retract the reaction.
                Pass list of int or str to react multiple emojis.

            big (``bool``, *optional*):
                Pass True to set the reaction with a big animation.
                For message reactions only.
                Defaults to False.
                
            add_to_recent (``bool``, *optional*):
                Pass True if the reaction should appear in the recently used reactions.
                This option is applicable only for users.

        Returns:
            :obj:`~pyrogram.types.MessageReactions`: On success, True is returned.
