I have two types of pods A and B

Pod Type A

apiVersion: v1
kind: Pod
metadata:
  name: A
  labels:
    environment: production
spec:
...

Pod Type B

apiVersion: v1
kind: Pod
metadata:
  name: B
  labels:
    environment: production
spec:
...

And a NetworkPolicy (still don't know the proper way to use podselection)

apiVersion: networking.k8s.io/v1
kind: NetworkPolicy
metadata:
  name: default-deny-all
spec:
  podSelector: {"A", "B"}
  policyTypes:
  - Ingress
  - Egress

Question : How do I define a single NetworkPolicy to limit traffic to only A & B pods (both ingress & egress) using a 'NetworkPolicy' in Kubernetes
