Ray cluster google cloud storage access

Related to: Google cloud storage access from worker, however the content seems outdated, since it uses serviceAccounts in the config.

I see in this PR serviceAccounts field is deprecated? [Feature] Add service account section in helm chart by ducviet00 · Pull Request #969 · ray-project/kuberay · GitHub

Also the new serviceAccountName is a Kubernetes service account and here it’s a service account in google cloud.

Is there an example for this using helm chart? I see in the helm template there is only serviceAccountName, but noserviceAccounts.
