Whitelist filter with k8s Gateway API GCP

k8s Ingress allows to filter IPs through annotation nginx.ingress.kubernetes.io/whitelist-source-range.

How can i to do the same through Gateway Api in GCP? https://cloud.google.com/kubernetes-engine/docs/concepts/gateway-api

I have not found any exemples of such behaviour for Gateway Api

Allow listing IP addresses is enforced via Cloud Armor policies. For example, you can use a rule like inIpRange(origin.ip, '198.51.100.0/24') in a Cloud Armor security policy.

With the Gateway API, you can then use gateway policies to attach a Cloud Armor policy to your Gateway:

apiVersion: networking.gke.io/v1
kind: GCPBackendPolicy
metadata:
  name: my-backend-policy
  namespace: lb-service-namespace
spec:
  default:
    securityPolicy: example-security-policy
  targetRef:
    group: ""
    kind: Service
    name: lb-service
