how can i download a directory from a server via SFTP/SCP to a zip file

I don't know how to do this using SSH.NET

namespace ConsoleApp1
{
    class Program
    {
        static void Main(string[] args)
        {

            var connectionInfo = new ConnectionInfo("192.168.133.13", "user",
                                        new PasswordAuthenticationMethod("isaque.neves", "pass"));
            using (var client = new SftpClient(connectionInfo))
            {
                client.Connect();
                DownloadDirectory(client,"/var/www/teste", @"C:\MyCsharpProjects\fsbackup\download");
             
            }

            Console.WriteLine("end");
        }

        public static void DownloadDirectory( SftpClient sftpClient, string sourceRemotePath, string destLocalPath)
        {
            Directory.CreateDirectory(destLocalPath);
            IEnumerable<SftpFile> files = sftpClient.ListDirectory(sourceRemotePath);
            foreach (SftpFile file in files)
            {
                if ((file.Name != ".") && (file.Name != ".."))
                {
                    string sourceFilePath = sourceRemotePath + "/" + file.Name;
                    string destFilePath = Path.Combine(destLocalPath, file.Name);
                    if (file.IsDirectory)
                    {
                        DownloadDirectory(sftpClient, sourceFilePath, destFilePath);
                    }
                    else
                    {
                        using (Stream fileStream = File.Create(destFilePath))
                        {
                            sftpClient.DownloadFile(sourceFilePath, fileStream);
                        }
                    }
                }
            }
        }
    }
}

I already did it in rust, but I don't know how to do it using SSH.NET
