Grafana use GKE LoadBalancer as HTTPS

Hi everyone, I have this kind of config in my grafana.ini but I think it’s not reflecting. I want to use Grafana in my GKE as https and I’ve already indicated the protocol to use https, I’ve already created ssl certificates and it’s in my cloud shell. Does anyone know how to run grafana in https? thanks.
