I'm trying to add Azure MSAL Authentication to an existing Blazor WASM application that already handles authentication with JWT. But if I register a custom AuthenticationStateProvider I use, blazor throw at runtime:

Unhandled exception rendering component: Specified cast is not valid. System.InvalidCastException: Specified cast is not valid.

Looking through sources, It seems it throws because an MSAL class expects that IServiceProvider returns an IRemoteAuthenticationService<TRemoteAuthenticationState> as AuthenticationStateProvider see
