    r"""Creates a new tweet, optionally including a poll or a quote tweet,

    This function sends a POST request to the Twitter API to create a new
    tweet. The tweet can be a text-only tweet, or optionally include a poll
    or be a quote tweet. A confirmation prompt is presented to the user
    before the tweet is created.

    Args:
        text (str): The text of the tweet. The Twitter character limit for
            a single tweet is 280 characters.
        poll_options (Optional[List[str]]): A list of poll options for a
            tweet with a poll.
        poll_duration_minutes (Optional[int]): Duration of the poll in
            minutes for a tweet with a poll. This is only required
            if the request includes poll_options.
        quote_tweet_id (Optional[Union[int, str]]): Link to the tweet being
            quoted.

    Returns:
        str: A message indicating the success of the tweet creation,

        You can only provide either the `quote_tweet_id` parameter or
        the pair of `poll_duration_minutes` and `poll_options` parameters,
