Before using: First verify the rule exists using 'List ACL Rules', or create it using 'Create ACL Rule (Insert)'.

Note: Due to Google API limitations with domain-type ACL rules, this action automatically falls back to UPDATE if PATCH fails.

In the response, hidden invitations can be identified by an attendee entry with attendees[].self==true and attendees[].responseStatus=="needsAction". TIMEZONE NOTE: If results are unexpectedly empty when filtering by time, check that your timeMin/timeMax timezone offsets match the calendar's timezone. UTC times may not align with local calendar dates.

Return a unified event list across all calendars in the user's calendar list for a given time range. Use when you need a single view of all events across multiple calendars.
