I am trying to create a Cron job programmatically in the CloudScheduler Google Cloud Platform using the following API explorer.

Reference: Cloud Scheduler Documentation

Even though I have given the user Owner permission and verified it in Policy Troubleshooter that it has cloudscheduler.jobs.create, I am still getting the following error.

{
  "error": {
    "code": 403,
    "message": "The principal (user or service account) lacks IAM permission \"cloudscheduler.jobs.create\" for the resource \"projects/cloud-monitoring-saurav/locations/us-central\" (or the resource may not exist).",
    "status": "PERMISSION_DENIED"
  }
}
