Get cluster ca certificate Azure ARM template ManagedClusters - azure

Question

How can I get the cluster ca certificate from the arm template for some ManagedClusters?
In terraform we use:
azurerm_kubernetes_cluster.aks_cluster.kube_config.0.cluster_ca_certificate
But in ARM I can't find it anywhere.
Can you please give some help?
Thanks
