I can successfully create a scheduled event no problem but whenever I try to use .createInviteURL(<channel>) it does not work. I've tried many permutations and it either says that the event hasn't been created yet (not a function), the event is still an unreturned promise, or that I can't do it before it's initialized. awaiting the event creation or using .then() hasn't worked. I would just love an example of what it looks like successfully done.
