  (Optional) A list of additional identities to assign roles at the project level for the fleet project. Use the following formats for specific Kubernetes identities:

  - **Specific Service Account:** For all Pods using a specific Kubernetes ServiceAccount:
    `principal://iam.googleapis.com/projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/PROJECT_ID.svc.id.goog/subject/ns/NAMESPACE/sa/SERVICEACCOUNT`

  - **Namespace-Wide Access:** For all Pods in a namespace, regardless of the service account or cluster:
    `principalSet://iam.googleapis.com/projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/PROJECT_ID.svc.id.goog/namespace/NAMESPACE`

  - **Cluster-Wide Access:** For all Pods in a specific cluster:
    `principalSet://iam.googleapis.com/projects/PROJECT_NUMBER/locations/global/workloadIdentityPools/PROJECT_ID.svc.id.goog/kubernetes.cluster/https://container.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/clusters/CLUSTER_NAME`

  Note: Namespace-Wide Access is Granted for all namespace created with `namespace_ids`.
