SPA + .NET Core Web API using SDK

I am looking for an example of an SPA (preferably angular) calling a .NET Core Web API where the Web API uses the Auth0.AspNetCore.Authentication package/SDK. I have followed the architecture setup etc in Single-Page Applications with API but cannot get it to work. I do not want to use any rules/policies at this point in time.

I would ideally like a step by step guide but know this is a stretch!
