Lens - Metrics not available at the moment

For any of you who have the same issue, you can use my ClusterRole.yml here which is based on the PR:

kind: ClusterRole
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: lens-read-metrics
rules:
  - apiGroups:
      - ""
    resources:
      - services/proxy
    verbs:
      - get
      - list
      - watch

You can bind this ClusterRole with your newly created service accounts with:

kind: RoleBinding
apiVersion: rbac.authorization.k8s.io/v1
metadata:
  name: lens-read-metrics
  namespace: lens-metrics # this is the namespace where Lens creates its metrics services by default
subjects:
  - kind: ServiceAccount
    name: <put your account name here>
    namespace: <your service account namespace>
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
