        Need to finish this

        [X] - This function should fetch a token, check if the token is valid, and obtain a refresh token if
        it has expired.

        Then do the real work.

        1. Check the queue - Done
        2. If there is an item, get the data - Done
        3. Evaluate if it is schedulable - Done
        4. Get the events and iterate each one - Done
        5. Starting with the message - Done
        6. Get the contact - Done
        7. Send the message
        8. Record the message event response - Added, not used
        9. Add to scheduler
