        If a message is a part of a message album, then it can be edited only to a photo or a video. Otherwise, the
        message type can be changed arbitrarily.

        Parameters:
            chat_id (``int`` | ``str``):
                Unique identifier (int) or username (str) of the target chat.
                For your personal cloud (Saved Messages) you can simply use "me" or "self".
                For a contact that exists in your Telegram address book you can use his phone number (str).

            message_id (``int``):
                Message identifier in the chat specified in chat_id.

            media (:obj:`InputMedia`):
                One of the InputMedia objects describing an animation, audio, document, photo or video.

            reply_markup (:obj:`InlineKeyboardMarkup`, *optional*):
                An InlineKeyboardMarkup object.

        Returns:
            :obj:`Message`: On success, the edited message is returned.

        Raises:
            RPCError: In case of a Telegram RPC error.
