Get RequiredAttendee (Required) from the Meeting (appointment) table – Power Automate / Dataverse

Below is the sample flow we can use to retrieve the Required (requiredattendees) field’s value from the Meeting table (on the update of the record).

Here we are triggering the flow, if there is an update in the subject field of the meeting record.

Then using the List rows action we are fetching the Activity Parties record associated using the Appointment’s unique identifier and participation mask as 5.

More on participation type mask –

And in the last step, we are checking for all the associated Activity Party GUIDs for a specific GUID and then update the record or cancel the record.

Hope it helps..
