                Pass a callback function to view the file transmission progress.
                The function must take *(current, total)* as positional arguments (look at Other Parameters below for a
                detailed description) and will be called back each time a new file chunk has been successfully
                transmitted.

            progress_args (``tuple``, *optional*):
                Extra custom arguments for the progress callback function.
                You can pass anything you need to be available in the progress callback scope; for example, a Message
                object or a Client instance in order to edit the message with the updated progress status.

        Returns:
            :obj:`~pyrogram.types.Story` a single story is returned.

        Example:
            .. code-block:: python

                # Post story to your profile
                await app.send_story("me", "story.png", caption='My new story!')

                await app.send_story(123456, "story.png", caption='My new story!')

            ValueError: In case of invalid arguments.
