AddApiAuthorization with Angular login/register pages instead of MVC views

I'm using the following scaffolded example with angular and ASP.NET Identity with IdentityServer4.

dotnet new angular -o <output_directory_name>-au Individual

The implementation is amazing, because it uses the recommended code with PKCE with angular OIDC client, which I tried to do myself, but it's way more code and it doesn't look as good as Microsoft's.

I want to use angular login/register pages instead of the default MVC views. Is that possible? I'm aware that what they did is also a separate part of the project, but I still want to use angular views. My angular and ASP.NET Core projects are completely separate and I don't use services.AddSpaStaticFiles which optimizes angular and starts angular at same port with the ASP.NET Core.
