I have to enroll multiple devices in Azure Device provisioning service and I am using group enrollment to achieve the same. I have created a self signed X509 certificate and enrollment group too. I registered a simulated device to the group using the sample code. I want to create another simulated device with same certificate and enroll in group. Is that possible? The input to the sample app is the Id scope of device provisioning service and the certificate. How can I add another device.

    if (string.IsNullOrWhiteSpace(s_idScope))

    {

        Console.WriteLine("ProvisioningDeviceClientX509 <IDScope>");

        return 1;

    }



    X509Certificate2 certificate = LoadProvisioningCertificate();



    using (var security = new SecurityProviderX509Certificate(certificate))





    {

        ProvisioningDeviceClient provClient =

            ProvisioningDeviceClient.Create(GlobalDeviceEndpoint, s_idScope, security, transport);



        var sample = new ProvisioningDeviceClientSample(provClient, security);

        sample.RunSampleAsync().GetAwaiter().GetResult();

    }



    return 0;

}



    private static X509Certificate2 LoadProvisioningCertificate()

{

    string certificatePassword = ReadCertificatePassword();



    var certificateCollection = new X509Certificate2Collection();

    certificateCollection.Import(s_certificateFileName, certificatePassword, X509KeyStorageFlags.UserKeySet);



            X509Certificate2 certificate = null;



            foreach (X509Certificate2 element in certificateCollection)

            {

                Console.WriteLine($"Found certificate: {element?.Thumbprint} {element?.Subject}; PrivateKey: {element?.HasPrivateKey}");

                if (certificate == null && element.HasPrivateKey)

                {

                    certificate = element;

                }

                else

                {

                    element.Dispose();

                }

            }



            if (certificate == null)

            {

                throw new FileNotFoundException($"{s_certificateFileName} did not contain any certificate with a private key.");

            }

            else

            {

                Console.WriteLine($"Using certificate {certificate.Thumbprint} {certificate.Subject}");

            }



            return certificate;

        }



        private static string ReadCertificatePassword()

        {

            var password = new StringBuilder();

            Console.WriteLine($"Enter the PFX password for {s_certificateFileName}:");



            while (true)

            {

                ConsoleKeyInfo key = Console.ReadKey(true);

                if (key.Key == ConsoleKey.Backspace)

                {

                    if (password.Length > 0)

                    {

                        password.Remove(password.Length - 1, 1);

                        Console.Write("b b");

                    }
