Remove Attendees from Events when Duplicating (Google Calendar)

When you drag-duplicate an event containing attendees, you likely don’t want the attendees copied to the new event. Or at least you’ll want to reset their “accepted” status. This action removes the attendee object entirely; you could go further and edit just event acceptance by examining the properties of the event.attendees object. If you’re going to change the event’s calendar after dragging, apply this action to the origin calendar, not the destination calendar: the On Event Create is fired as soon as the event is rendered on-screen (which happens right after it’s duped and is still in the original calendar).

event.attendees = [];
