How to secure Blazor WebAssembly application and WebApi using Windows Authentication

I am working on implementing security to Blazor WebAssembly .Net core hosted application. I need to secure client as well as WebAPI (to be hosted on IIS). As a policy decision, the team has decided to use Windows authentication instead of Azure AD for now.

I see multiple articles on the internet describing how to implement security using Azure AD. But less help is available about securing Blazor WASM using Windows Authentication. Any help in this regard will be highly appreciated.
