Extendscript Debugger for VSCode: Debug output?

Hi everybody,

I am trying to write a script for Illustrator with the Extendscript Debugger for VSCode. And I want to put out some debugging messages. But I cannot figure out how to do that.

I tried print(), $.writeln(), console.log() and a few other things. But none of it works. All all these functions and objects are apparently undefined.

So, how do you make a debug output?

Thanks!
