          To delete an external access firewall rule called `my-external-access-rule` in project `my-project` and region `us-west2` associated with network policy `my-network-policy`, run:

            $ {command} my-external-access-rule --location=us-west2 --project=my-project --network-policy=my-network-policy

          Or:

            $ {command} my-external-access-rule --network-policy=my-network-policy

          In the second example, the project and the location are taken from gcloud properties core/project and compute/region respectively.
