What should we build?

In docs/workshops/beginner/start-applications.md, I have run into some issues with setting OAUTH2_ACTIVE to false. The frontend reports these errors as CORS errors, which leads to some tricky debugging.

I would recommend mentioning in the tutorial that this error is easy to run into if running on a standard localhost setup. It could be mentioned for instance that running with this value set to false can be done with OAUTH2_ACTIVE=false uvicorn --host localhost --port 8080 main:app.

Relevant pseudo code
