Need to set cipher suite at the code to get token in C#

using System;
using System.Net;

class Program
{
    static void Main()
    {
        // Replace with the actual URL you want to connect to
        string targetUrl = "https://example.com";

        try
        {
            // Set the security protocol to TLS 1.2 (compatible with 2012 R2)
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

            // Replace with the Cipher Suites you want to use
            string[] cipherSuites = { "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384", "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256" };
            
            // Set the Cipher Suites
            ServicePointManager.Expect100Continue = true;
            ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

            // Disable older protocols for enhanced security
            ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Tls;
            ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl3;

            // Set the Cipher Suites
            ServicePointManager.SecurityProtocol &= ~SecurityProtocolType.Ssl2;

            ServicePointManager.ServerCertificateValidationCallback += (sender, certificate, chain, sslPolicyErrors) => true;

            // Create a web request
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(targetUrl);

            // Set the Cipher Suites on the request
            request.CipherSuites = cipherSuites;

            // Perform the request
            using (HttpWebResponse response = (HttpWebResponse)request.GetResponse())
            {
                // Process the response if needed
                Console.WriteLine("Response Status: " + response.StatusCode);
            }
        }
        catch (Exception ex)
        {
            Console.WriteLine("Error: " + ex.Message);
        }
    }
}
 

The code sets the security protocol to TLS 1.2 and specifies two Cipher Suites (TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 and TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256). You should replace these values with the Cipher Suites that you want to use.
