Do you need to use the AuthenticationStateProvider? See here: https://learn.microsoft.com/en-us/aspnet/core/blazor/security/?view=aspnetcore-8.0#authenticationstateprovider-service

You don't typically use AuthenticationStateProvider directly. Use the AuthorizeView component or Task<AuthenticationState> approaches described later in this article. The main drawback to using AuthenticationStateProvider directly is that the component isn't notified automatically if the underlying authentication state data changes.
