I have created own project in openshift 4.13 cluster. I tried to monitor my project metrics but unable to do that.

Followed below steps:

1. Enabled user monitoring referred by https://docs.openshift.com/container-platform/4.13/observability/monitoring/enabling-monitoring-for-user-defined-projects.html#enabling-monitoring-for-user-defined-projects_enabling-monitoring-for-user-defined-projects
2. Created servicemonitor in openshift-user-workload-monitoring. PFB
   apiVersion: monitoring.coreos.com/v1
   kind: ServiceMonitor
   metadata:
   name: prometheus-ns
   spec:
   endpoints:
   • interval: 5s
     port: “8085”
     scheme: http
     path: /metrics
     namespaceSelector:
     matchNames:
     • ns
       selector: {}
3. I have checked prometheus logs. no errors
4. I have check in prometheus target its not available.

Could you please help me on this. how to monitor user projects in openshift 4.13.
