I'm trying to use changes to a particular AAD group as an event trigger for an Azure function I'm creating. I've created filters within the event subscription relying on the documentation of JSON schemas for changes to AAD groups as here. No matter my attempts with the filters, removing and adding someone to the group isn't triggering the function - which makes me believe I either don't understand the monitoring for the function usage or the filters I'm trying to use.
In filters, I've tried setting the event type to: Microsoft.Graph.GroupUpdated and also leaving it blank, filtering by subject with "Groups/<group id>", and targeting the id in the advanced filters at the bottom with data.id string contains the <group id>.
Any assistance that anyone could provide here to trigger this particular event for my function would be greatly appreciated.
