Configuration Help Please

I am new to Node-Red, attempting to transition from Claris Connect. I have set up a Node-Red server in Azure and have successfully created some simple flows.

My issues is that my install does not appear to be configured to accept outside traffic on 80 or 443. I followed the setup instructions for Azure but there was not configuration instructions to turn on the web server and allow Node-Red access.

Can anyone point the way to this setup for me please?
