How to create GCP policy that will install ops-agent on all Ubuntu 22.04 VMs?

I'm trying to create a policy that will install ops-agent on all Ubuntu 22.04 automatically, so I've created this OS policy assignment and it seems it's been rolled out successfully but I still see my VMs as Non-compliant, what is that I'm doing wrong?
Command:gcloud compute os-config os-policy-assignments describe ops-agent-ubuntu-22-stag-os-policy --project=project-stag
Result:

and when trying to check the reports it doesn't show any reason for the failure
