For reference this is what a SelfSubjectReviews response for cluster-admin looks like:

{
  "metadata": { "creationTimestamp": null },
  "spec": {},
  "status": {
    "resourceRules": [
      {
        "verbs": ["create"],
        "apiGroups": ["authorization.k8s.io"],
        "resources": ["selfsubjectaccessreviews", "selfsubjectrulesreviews"]
      },
      { "verbs": ["*"], "apiGroups": ["*"], "resources": ["*"] }
    ],
    "nonResourceRules": [
      {
        "verbs": ["get"],
        "nonResourceURLs": [
          "/healthz",
          "/livez",
          "/readyz",
          "/version",
          "/version/"
        ]
      },
      {
        "verbs": ["get"],
        "nonResourceURLs": [
          "/api",
          "/api/*",
          "/apis",
          "/apis/*",
          "/healthz",
          "/livez",
          "/openapi",
          "/openapi/*",
          "/readyz",
          "/version",
          "/version/"
        ]
      },
      { "verbs": ["*"], "nonResourceURLs": ["*"] }
    ],
    "incomplete": true,
    "evaluationError": "webhook authorizer does not support user rule resolution"
  }
}
