pod identity on aks cluster crreation - kubernetes

Question

Right now, it's impossible to have assigned user assigned identities on arm templates (and terraform) on cluster creation. I already tried a lot of things, and updates works great, after inserting manually with:
az aks pod-identity add --cluster-name my-aks-cn --resource-group myrg --namespace myns --name example-pod-identity --identity-resource-id /subscriptions/......
But, I want to have this done at once, with the deployment, so I need to insert the pod user identities to the cluster automatically. I also tried to run the command using the DeploymentScripts but the deployment scripts are not ready to use preview aks extersion.
My config looks like this:
{
"type": "Microsoft.ContainerService/managedClusters",
"apiVersion": "2021-02-01",
"name": "[variables('cluster_name')]",
"location": "[variables('location')]",
"dependsOn": [
"[resourceId('Microsoft.Network/virtualNetworks', variables('vnet_name'))]"
],
"properties": {
....
"podIdentityProfile": {
"allowNetworkPluginKubenet": null,
"enabled": true,
"userAssignedIdentities": [
{
"identity": {
"clientId": "[reference(resourceId('Microsoft.ManagedIdentity/userAssignedIdentities', 'managed-indentity'), '2018-11-30').clientId]",
"objectId": "[reference(resourceId('Microsoft.ManagedIdentity/userAssignedIdentities', 'managed-indentity'), '2018-11-30').principalId]",
"resourceId": "[resourceId('Microsoft.ManagedIdentity/userAssignedIdentities', 'managed-indentity')]"
},
"name": "managed-indentity",
"namespace": "myns"
}
],
"userAssignedIdentityExceptions": null
},
....
},
"identity": {
"type": "SystemAssigned"
}
},
I'm always getting the same issue:
"statusMessage": "{\"error\":{\"code\":\"InvalidTemplateDeployment\",\"message\":\"The template deployment 'deployment_test' is not valid according to the validation procedure. The tracking id is '.....'. See inner errors for details.\",\"details\":[{\"code\":\"PodIdentityAddonUserAssignedIdentitiesNotAllowedInCreation\",\"message\":\"Provisioning of resource(s) for container service cluster-12344 in resource group myrc failed. Message: {\\n \\\"code\\\": \\\"PodIdentityAddonUserAssignedIdentitiesNotAllowedInCreation\\\",\\n \\\"message\\\": \\\"PodIdentity addon does not support assigning pod identities on creation.\\\"\\n }. Details: \"}]}}",

The Product team has shared the answer here: https://github.com/Azure/aad-pod-identity/issues/1123
which says:
This is a known limitation in the existing configuration. We will fix
this in the V2 implementation.
