Description of problem:

I am trying to deploy the observability components by following the official docs at:
https://access.redhat.com/documentation/en-us/red_hat_advanced_cluster_management_for_kubernetes/2.1/html/observing_environments/observing-environments

Right off the bat, the endpoint-observability-operator pod throws RBAC related errors, see below.

Version-Release number of selected component (if applicable):

rhacm-2.1

How reproducible:

Additional info:

I "fixed" it by providing the operator with the full permissions to Kubernetes APIs by creating these resources:

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: endpoint-observability-operator-rb-fix
roleRef:
  apiGroup: rbac.authorization.k8s.io
  kind: ClusterRole
  name: endpoint-observability-operator-fix
subjects:
- kind: ServiceAccount
  name: endpoint-observability-operator-sa
  namespace: open-cluster-management-addon-observability

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
  name: endpoint-observability-operator-fix
rules:
- apiGroups:
  - '*'
