Azure AKS – Nginx application routing addon with private IP setup

Hi, I am trying to setup ngnix based application routing add-on in AKS using below link.

learn.microsoft.com/en-us/azure/aks/create-nginx-ingress-private-controller

I used the below yaml to apply the custom add-on

I am getting below error

error: unable to recognize “nginx-internal-controller.yaml”: no matches for kind “NginxIngressController” in version “approuting.kubernetes.azure.com/v1alpha1

Is there newer/updated way to configure above?
