Jitsi Desktop App Events, Incomming call, external app won't start

I have Jitsi Desktop app on Windows. I want to set Incomming call event to point on external application to pass parameters from calls. I wrote sample app in C#:

static void Main(string[] args)

            var argsFromJitsi = string.Empty;

            if (args != null)
                for (int i = 0; i < args.Length; i++)
                    argsFromJitsi += $" {args[i]}";

            Console.WriteLine($"Arguments: {argsFromJitsi}");

When I call on Jitsi from external number ( my Jitsi is integrated with FreePbx and works) my app in C# wont to run. I get error. When I set Notepad++.exe in Incomming call event it works. I wrote simple app in Python but it won’t work. Only Notepad++.exe starting but I can’t see paramters from calls.


I need to pass paramteres from call when someone calls to me on my Jitsi, how can I do that ?
