        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.

            caption (``str``):

            parse_mode (``str``, *optional*):
                By default, texts are parsed using both Markdown and HTML styles.
                You can combine both syntaxes together.
                Pass "markdown" or "md" to enable Markdown-style parsing only.
                Pass "html" to enable HTML-style parsing only.
                Pass None to completely disable style parsing.

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

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

        Example:
            .. code-block:: python

                app.edit_message_caption(chat_id, message_id, "new media caption")
