        If a message is a part of a message album, then it can be edited only to a photo or a video. Otherwise,
        message type can be changed arbitrarily. When inline message is edited, new file can't be uploaded.
        Use previously uploaded file via its file_id or specify a URL. On success, if the edited message was sent
        by the bot, the edited Message is returned, otherwise True is returned.

        Args:
            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:`InputMediaAnimation` | :obj:`InputMediaAudio` | :obj:`InputMediaDocument` | :obj:`InputMediaPhoto` | :obj:`InputMediaVideo`)
                One of the InputMedia objects describing an animation, audio, document, photo or video.

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

        Returns:
            On success, the edited :obj:`Message <pyrogram.Message>` is returned.

        Raises:
            :class:`Error <pyrogram.Error>` in case of a Telegram RPC error.
