Вызываю запрос Graph API ME.

Я пытаюсь вызвать вызов делегата, используя c # и консольное приложение. Прямо сейчас это ошибка, которую я получил "Code: generalExceptionrnMessage: An error occurred sending the request.rn"

Это консоль c #, пытающаяся вызвать graph api.

 static void Main(string[] args)
        {
            try
            {
                RunAsync().GetAwaiter().GetResult();
            }
            catch(Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
            Console.WriteLine("Press any key to exit");
            Console.ReadKey();
        }

        private static async Task RunAsync()
        {
            string secretKey = <secretKey>;
            string appId = <clientID>;
            string tenantId = <tenantID>;
            string tokenUrl = "https://login.microsoftonline.com/common/oauth2/v2.0/token";
            List<string> scopeURL = new List<string>();
            scopeURL.Add("https://graph.microsoft.com/.default");

            Console.WriteLine("Enter a username");
            string username = Console.ReadLine();
            Console.WriteLine("Enter a password");
            var password = GetConsoleSecurePassword();

            var httpClient = new HttpClient();

            IPublicClientApplication publicClientApplication = PublicClientApplicationBuilder
            .Create(appId)
            .WithTenantId(tenantId)
            .Build();

            UsernamePasswordProvider authProvider = new UsernamePasswordProvider(publicClientApplication, scopeURL);

            GraphServiceClient graphClient = new GraphServiceClient(authProvider);
            try
            {
                User me = await graphClient.Me.Request()
                            .WithUsernamePassword(username, password)
                            .GetAsync();

                var books = await graphClient.BookingBusinesses.Request().GetAsync();
                foreach (var book in books)
                {
                    Console.WriteLine(book.DisplayName);
                }
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }

        private static SecureString GetConsoleSecurePassword()
        {
            SecureString pwd = new SecureString();
            while (true)
            {
                ConsoleKeyInfo i = Console.ReadKey(true);
                if (i.Key == ConsoleKey.Enter)
                {
                    break;
                }
                else if (i.Key == ConsoleKey.Backspace)
                {
                    pwd.RemoveAt(pwd.Length - 1);
                    Console.Write("b b");
                }
                else
                {
                    pwd.AppendChar(i.KeyChar);
                    Console.Write("*");
                }
            }
            return pwd;
        }
  

Мне бы очень хотелось иметь возможность вызывать bookingBusiness, однако я даже не могу прочитать своего пользователя.

Это мое разрешение для приложения. Чего мне не хватает?

Как и просили
