az network bastion rdp --auth-type AAD - Unable to change AAD user after first logon

### Describe the bug

Not sure if this is a bug in documentation or implementation... It could also be "by design" and should instead be a Feature request.

When I authenticate using AAD with the native RDP client it works fine, but I cannot find a way to change the AAD identity since I get automatically signed in to the remote VM automatically after first successful sign-in.

### Related command

az network bastion rdp --auth-type AAD

### Errors

No prompted to sign-in

### Issue script & Debug output

In the debug output I see...
msal.application: Cache hit an AT
msal.telemetry: Generate or reuse correlation_id: 59c10bc4-44dd-492f-a1bb-171ae732b55e

### Expected behavior

Some way to be able to clear the cached RDP credentials to sign-in again as another user.
