Authorization conventions .NET Core: BlazorWebAssembly

[Dmo01]

I am using .NET 6.0, but since I am following the .NET 5.0 structure with a separate Startup.cs and Program.cs I used this link as a reference. Thanks in advance for any help. BTW, I saw where Labels can be added but I was not able to add them.

I have a custom policy that I have added to my common library. Something like this.

options.AddPolicy("ManageUsers", policy => policy.RequireAssertion
(
    context => context.User.HasClaim((c => c.Type == "Edit" || c.Type == "View")))
);

Then in my razor page, in my client project, I have the following. This works. A forbidden error is thrown if you do not have the ManageUsers policy.

@attribute[Authorize(Policy = " ManageUsers")]

But when I added logic in my Web.Server.Startup.cs like this, I never get the forbidden error. Since I am using BlazorWebAssembly I think I need to add this logic to Web.Client.Program.cs instead but I am not sure how.

services.AddRazorPages(options =>
{
    options.Conventions.AuthorizePage("/Contact", "AccessManageEFMPUsersPage");
});

This is how my current Web.Client.Program.cs is structured

public static async Task Main(string[] args)
{
    var builder = WebAssemblyHostBuilder.CreateDefault(args);
    builder.RootComponents.Add<App>("#app");

    builder.Services.AddScoped(sp => new HttpClient { BaseAddress = new Uri(builder.HostEnvironment.BaseAddress) });
    builder.Services.AddAuthorizationCore();
    await builder.Build().RunAsync();
}
