async def remove_reaction(self, emoji, member):
        """|coro|

        Remove a reaction by the member from the message.

        The emoji may be a unicode emoji or a custom guild :class:`Emoji`.

        If the reaction is not your own (i.e. ``member`` parameter is not you) then
        the :attr:`~Permissions.manage_messages` permission is needed.

        The ``member`` parameter must represent a member and meet
        the :class:`abc.Snowflake` abc.

        Parameters
        ------------
        emoji: Union[:class:`Emoji`, :class:`Reaction`, :class:`PartialEmoji`, :class:`str`]
            The emoji to remove.
        member: :class:`abc.Snowflake`
            The member for which to remove the reaction.

        Raises
        --------
        HTTPException
            Removing the reaction failed.
        Forbidden
            You do not have the proper permissions to remove the reaction.
        NotFound
            The member or emoji you specified was not found.
        InvalidArgument
            The emoji parameter is invalid.
