Group Calendar Event 'Add to Calendar' in Office Graph
We need to use the Office Graph API to enable users to add events in an Office 365 Group calendar to their personal calendar. This would simulate the 'Add to calendar' option from within the Outlook calendar. Unless I'm missing something, this is not currently possible as the only root to the event is through option below but the 'Accept' command doesn't work as it's operating as the Group no as the user - https://graph.microsoft.com/v1.0/groups/<GroupID/events/<EventID>/accept.
Any attempt to access the event by the Event ID has failed in an Office 365 Group calendar.
