Hi, is there a way to view a allow/deny traffic from source to destination on viz dashboard or CLI?

For example, we have applied Server profile and ServerAuthorization policy to service A, B & C. Service A & B are located in namespace X and service C is located in namespace Y. The policy attached to service C is only allowed service A. So, the policy will block when service B talks to service C. We would like to visualize or proof that the policy clearly deny the traffic from service B which is useful for troubleshooting or investigation.

Yes, check out the `linkerd viz authz` command. You can see some examples of how to use this command in [this tutorial](https://linkerd.io/2.14/tasks/configuring-per-route-policy/#creating-a-server-resource).
