Elastic-agent kubernetes-integration does not collect kubernetes metrics

Hello team,

I have Elastic Agent deployed with ECK, but for some reason I don't get the kubernetes metrics. Instead I see this error in the logs:

{"log.level":"info","@timestamp":"2023-10-10T14:55:42.666Z","message":"could not retrieve cluster metadata: fail to get kubernetes cluster metadata: unable to retrieve cluster identifiers","component":{"binary":"metricbeat","dataset":"elastic_agent.metricbeat","id":"kubernetes/metrics-default","type":"kubernetes/metrics"},"log":{"source":"kubernetes/metrics-default"},"log.origin":{"file.line":740,"file.name":"util/kubernetes.go"},"service.name":"metricbeat","ecs.version":"1.6.0","ecs.version":"1.6.0"}

this is my elastic-agent-clusterrolebinding.yaml

apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRoleBinding
metadata:
  name: qa-apm-elastic-agent
subjects:
- kind: ServiceAccount
  name: qa-apm-elastic-agent
  namespace: qa-apm

And this is my cluster role : cat elastic-agent-clusterrole.yaml

Not sure if this is a permission issue. I can provide my kubernetes-integration file if required.
