'Azure policies(gatekeeper) monitoring on AKS via Prometheus and Grafana

I have enabled azure policies via terraform and applied to AKS cluster. I can see pods are deployed, up and running. I applied in-built initiative here too with effect "audit" to test out how azure policies works on aks cluster.

$ kubectl get pods -n gatekeeper-system
NAME                                    READY   STATUS    RESTARTS   AGE
gatekeeper-audit-77754c7d8-g44qb        1/1     Running   0          44h
gatekeeper-controller-78cff9c89-7pftn   1/1     Running   0          44h
gatekeeper-controller-78cff9c89-8dsfg   1/1     Running   0          44h

I found a dashboard https://grafana.com/grafana/dashboards/15763

But some of the metrics are different/missing. Not sure, because, azure managing this gatekeeper!?. I see below some panel are displaying and metrics are available in prometheus. For example below opa_scorecard_constraint_violations not avilable. enter image description here
