Switching to Ws-Federation authentication

[SvdSinner]

I need to modify the BlazorHero template to use Ws-Federation authentication instead of maintaining usernames/passwords inside the application.
Firstly, how do I stop the app from going to the login screen?
Secondly, how/where do I tell the user service what I want it to return for the current user? (I can write the code to populate the BlazorHeroUser from WS-Federation, but I'm having a hard time determining where I need to do that.)
