pod "aad-pod-identity-nmi-xxx" CrashLoopBackOff after "helm install pod-identity aad-pod-identity/aad-pod-identity"

[XinCai]

I've followed your guide step by step, and found out the AKS (v1.19.9) cluster was created with Network type (plugin):Kubenet

After install

helm install pod-identity aad-pod-identity/aad-pod-identity"

And I found there is one pod which is CrashLoopBackOff

After inspect pod log, it shows me this:

F0503 05:44:11.611397       1 main.go:82] AAD Pod Identity is not supported for Kubenet. Review https://azure.github.io/aad-pod-identity/docs/configure/aad_pod_identity_on_kubenet/ for more details.

I think i need to re-create the cluster with Azure CNI network plugin.
