Please if possible add here: https://kubernetes.io/docs/concepts/services-networking/network-policies/ at this paragraph: "Behavior of to and from selectors" a small working yaml example which shows that also with egress -to (now it's only shown with ingress -from) the - namespaceSelector: and - podSelector: specs can be added making simpler for developers and students to quickly pick up an example and use it. Thank you.
