Adding Entra ID authentication to a web app that utilizes Web PubSub in Azure

I'm trying to simply add Microsoft Entra ID for authentication to an Azure web app. I have a javascript chat-app using Web PubSub that worked perfectly using this example:

https://github.com/Azure/azure-webpubsub/tree/main/samples/javascript/chatapp/nativeapi

I followed the instructions here using the work-force configuration...

https://learn.microsoft.com/en-us/azure/app-service/scenario-secure-app-authentication-app-service?tabs=workforce-configuration

The instruction description says "No SDKs, specific languages, or changes to application code are required." I used the defaults and now the app will connect to chat server, but then the connection is terminated with the first message. I make up that Web PubSub needs to be authenticated to my web app, but I'm unsure how to get this done. Is that the problem? How do I resolve in the simplest method, preferably with no code changes?

Thank you,
Peter
