Use this API to add a bookmark to a session for an attendee.

You need to send true for query parameter joinSession if the attendee register/bookmark session before it's live.

If the attendee registers for a session after the session ended, then you need to send pastJoinSession as true within the query parameters.

If for the session allowedMinutesToJoinLate is set true, and you try to register after the session ended then recording of this session is not available, it's only available for the attendees who have watched the session when it's live.

This API can be used by authenticated users only, and it will require super admin/event admin/event staff/attendee level access.
