When the Outlook 365 when an event is added, updated or deleted is triggered for a 'deleted' action type the
GraphCalendarEventClientWithActionType only returns values for Action Type & id.
The other values return null.
It would be useful if the original metadata from the Event was returned.
Use Case : utilising a trigger condition were event category contains "Client Appointment".
Trigger condition applies for 'added' and 'updated' action type as "categories" value contains "Client Appointment"
Trigger condition does not apply for 'deleted' action type as category value returns as "categories": null
This means that instead of limiting triggers we need to have the flow trigger for all interactions so it can pick up when an event is deleted resulting in many more flow runs then is required.
