Configure the ArgoCD with GKE cluster

Hi

I am trying to install the argocd in GKE cluster and successfully installed, i can see services and running and i expose the service as NEG so that i can expose the argoCd with GCP load balancer, but i have to provide the health check config on the GCP load balancer , can anyone suggest that what is the port and endpoint for creating a health check for argocd on GCP loadbalancer

Thanks
