Calendar sync: When session canceled in Upheal, remove it in Google Calendar

When I cancel a session in Upheal, I want it to remove it from Google Calendar. Right now, when I cancel a session in Upheal, the session stays in Google Calendar, and I have to delete it manually there. Other apps offer this feature… If I cancel or change an appointment, it automatically removes the original time from my calendar. So I know the coding to do this exists.
