Correlation between Microsoft Graph Events and bookingBusiness Appointments

Hi everyone, I'm struggling with getting complete attendee information from calendar events. I can successfully get event details from the /events endpoint, but it lacks full attendee information and other details compared to the bookingBusiness/account-id/appointments endpoint. The problem is, I can't find a way to correlate and event and its various ID's and a booking appointment ID. Is there a recommended way to get full attendee details while working with calendar events? Any help would be appreciated!
