When can I mark an event participant as Optional?

An event's organizer can mark a participant as Optional if their attendance at the event isn't mandatory. This can be done while the organizer is inviting participants to join the meeting. If marked, the participant's event invitation will display an Optional tag, and they can then decide whether to attend.
