importEvent preserves an existing cross-system iCalendar UID during a
migration or synchronization. It imports an event silently; it is not a
replacement for creating and inviting guests.
Example
Inputs
iCalUID, summary, and schedule are required. All event-detail fields from
Create event
are supported except createMeet and sendUpdates; calendar defaults to
primary and account selects the Google account.
Output
Returns the importedCalendarEvent; see Get event. Google does not send invitations for imported attendee data. The iCalUID is a cross-calendar identity, while later Calendar actions use the returned provider id.
