Creates a contact group. If a group with the same name exists (case does not matter), that one is returned with created: false, so calling twice is safe.
Add contacts to it with Add contacts to a group.
Try it
Protects against doing it twice if you retry: a retry with the same key gets the first answer back instead of running again.
