How to control gnfd_create_folder

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "gnfd_create_folder": {
      "limits": [
        {
          "counter": "gnfd_create_folder_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
