How to make a grpc call to argo-cd server in same cluster

[thetruechar]

        import "github.com/argoproj/argo-cd/pkg/apiclient"
	cli, err := apiclient.NewClient(&apiclient.ClientOptions{
		ServerAddr: "argocd-server.argocd",
		PlainText: true,
		Insecure:  true,
	})
	if err != nil {
		log.Err(err).Send()
		return
	}
	closer, sessCli, err := cli.NewSessionClient() // will block here forever

I try to make a grpc call to the argocd-server deployed in same cluster in namepsace argocd, but it will block in creating new client, thank you for you help.
