+
+        This convenience method works with any valid file_id only.
+        It does the same as calling the relevant method for sending media using a file_id, thus saving you from the
+        hassle of using the correct method for the media the file_id is pointing to.
+
+        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).
+
+            file_id (``str``):
+                Media to send.
+                Pass a file_id as string to send a media that exists on the Telegram servers.
+
+            caption (``bool``, *optional*):
+                Media caption, 0-1024 characters.
+
+            parse_mode (``str``, *optional*):
+                Use :obj:`MARKDOWN <pyrogram.ParseMode.MARKDOWN>` or :obj:`HTML <pyrogram.ParseMode.HTML>`
+                if you want Telegram apps to show bold, italic, fixed-width text or inline URLs in your caption.
+                Defaults to Markdown.
+
+            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.
+
+            reply_markup (:obj:`InlineKeyboardMarkup` | :obj:`ReplyKeyboardMarkup` | :obj:`ReplyKeyboardRemove` | :obj:`ForceReply`, *optional*):
+                Additional interface options. An object for an inline keyboard, custom reply keyboard,
+                instructions to remove reply keyboard or to force a reply from the user.
+
+        Returns:
+            On success, the sent :obj:`Message <pyrogram.Message>` is returned.
+
+        Raises:
+            :class:`Error <pyrogram.Error>` in case of a Telegram RPC error.
