ASP.NET Core Identity, SSO with WSFederation

Question

I need to make my new ASP.NET Core Blazor WASM application authenticate with our on-prem ADFS/WSFederation servers. Specifically, it needs to automatically log-in users that are already logged into our AD domain, without making them go to a login page. Basic single sign on behavior. (This is how ASP.NET worked by default with ADFS/WSFederation)

I can get SSO to work without using Identity, and I get get Identity to use a log-in screen that will allow you to choose a WSFederation server as an external log-in provider, but that still begins at a log-in screen.

Can ASP.NET Core Identity work in an SSO configuration (no login screens appear for domain users), or is Identity built on the assumption that Log-in screens will be used? If it can be done, how is that set up? If I can't use Identity, can I still use other middleware like Authorization?
