What you're looking for is being deprecated. We need to use Cloud Console dashboards, here.
Official Message:
The open source Kubernetes Dashboard addon is deprecated for clusters on GKE and will be removed as an option in version 1.15. It is recommended to use the alternative Cloud Console dashboards described on this page.
