public class ServerAuthorizationMessageHandler : AuthorizationMessageHandler
{
    public ServerAuthorizationMessageHandler(IAccessTokenProvider provider, IConfiguration configuration,
        NavigationManager navigationManager)
        : base(provider, navigationManager)
    {
        var serverUrl = configuration["AppSettings:ServerUrl"];

        ConfigureHandler(
           authorizedUrls: new[] { serverUrl },
           scopes: new[] { "api://lkjlkj/ReadAccess" }
        );
    }
}

builder.Services.AddHttpClient("Server", client => client.BaseAddress = new Uri(serverUrl))
          .AddHttpMessageHandler<ServerAuthorizationMessageHandler>();

        builder.Services.AddMsalAuthentication(options =>
        {
            builder.Configuration.Bind("AzureAd", options.ProviderOptions.Authentication);
            options.ProviderOptions.DefaultAccessTokenScopes.Add("???????");
