Debugging while developing Java Script extensions

[Bending5FD2]

OS: Sonoma 14.0

I am developing an After Effects extension. 

I use for this CEP tools. 

My main problem is that I can't understand how to debug the dev process with the After Effects. 
Basically, I would like to write a line with something like "console.log("We have control over")" and see it in some kind of a console. However, I can't make it work.

I tried to open also the localhost with the port from .debug file, but it seems I can't even open the extension unless I prepare the production build. 

Please let me know where I can see some resources?

Thanks!

There is $.write and $.writeln in ExtendScript:
