Additional Notes#

• Time Zone Support: Ensure that the timeZone property is set when dealing with events across different time zones to prevent scheduling conflicts.
• Recurrence Rules: While recurrence rules can be associated with events, detailed usage of recurrence rules has been omitted in this document. Refer to the recurrence-related API documentation for more details.
• Attendees Management: The attendees property can be used to manage participants. Each attendee is represented by an EventParticipant object that includes details such as name, role, and attendance status.
