I am unable to find documentation to set the appropriate IAM permissions to a user to access, view and modify filters on this GCP API Metrics page: https://console.cloud.google.com/apis/api/firestore.googleapis.com/metrics
Does anyone know how this can be done with the minimal permissions required? Or if there is a role to it that is finer-grained than owner/editor/viewer.
The screen you shared is managed by the Service Usage API
. To be able to access it, you need the serviceusage.services.get
permission which is part of the Service Usage Viewer (roles/serviceusage.serviceUsageViewer)
role.
Check this link for further details about the service usage access controls.
