Hi there,
Execute me for asking these questions again but making them shorter:
1. Why a participant of a calendar event can add a comment by UI but
not API?
2. Similarly, why a participant of a calendar event can invite a guset
by UI but not API?
I was confused about these for a long time, who can answer me by some
examples workable?
Thank you very much!
Best wishes,
paul
