there is no angular code involved with windows authentication. all the docs are for oauth. to configure:
https://docs.microsoft.com/en-us/aspnet/core/security/authentication/windowsauth?view=aspnetcore-3.1&tabs=visual-studio
iif you use windows authentication with CORS, the preflight (OPTIONS) requests must be anonymous. You may need to allow anonymous and use middleware to force authentication when not a preflight. google for examples.
