Access Cancellation Reason with Power Automate

Is there any way to obtain the cancellation reason of a booking with power automate?

Cancel Reason should be accessible via AppointmentData according to the documentation: https://learn.microsoft.com/en-us/connectors/microsoftbookings/#when-an-appointment-is-cancelled

However, this is not the case. I've tried cancelling bookings via the app and the actual bookings page but this field is not present on the output of the trigger.

Any help with this would be great.

Thanks
