        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).

            media (List of :obj:`~pyrogram.types.InputMediaPhoto`, :obj:`~pyrogram.types.InputMediaVideo`, :obj:`~pyrogram.types.InputMediaAudio` and :obj:`~pyrogram.types.InputMediaDocument`):
                A list describing photos and videos to be sent, must include 2–10 items.

            disable_notification (``bool``, *optional*):
                Sends the message silently.
                Users will receive a notification with no sound.

            reply_to_message_id (``int``, *optional*):
                If the message is a reply, ID of the original message.

            schedule_date (:py:obj:`~datetime.datetime`, *optional*):
                Date when the message will be automatically sent.

            protect_content (``bool``, *optional*):
                Protects the contents of the sent message from forwarding and saving.

        Returns:
            List of :obj:`~pyrogram.types.Message`: On success, a list of the sent messages is returned.
