The code looks like…

    public class Client : BaseScript
    {
        private bool firstTick = false;

        public Client()
        {
            Tick += OnTick;

            EventHandlers.Add("chatMessage", new Action<int, string, string>(OnChatMessage));
        }

        private async Task OnTick()
        {
            await Delay(100);

            if (!firstTick)
            {
                firstTick = true;
            }
        }

        public void OnChatMessage(int id, string playerName, string message)
        {
            Debug.WriteLine("**** OnChatMessage ****");
            Debug.WriteLine("id: {0}", id);
            Debug.WriteLine("playerName: {0}", playerName);
            Debug.WriteLine("message: {0}", message);
        }

That code should be on the server side

Thank you @Briglair, I am rolling now.
