cannot specify virtual network when deploying APIM usnig CLI

The documentation is not clear on how a VNet integrated APIM service can be created.

I tried this:

_az login
az apim create --name "" --publisher-email "" --publisher-name "" --resource-group "" --virtual-network "External"_

The service created is not VNet integrated.

The section for "az apim create", specifically, the "--virtual-network" parameter needs to be better documented. There is no option to specify the virtual network and subnet you want to deploy the service into.

This was raised here as well:
