Scripting: running the code slowly (with PAUSEs?)

I am aware about the ability to add break points in visual code for example..

I would like for a different approach,

I am running a script that does multiple things during a short amount of time,

I would like it to "pause", between certains lines of the code to be able to watch what's happening,

I tried javascript codes, but they did not work:

// sleep(1000);
// setTimeout(() => { console.log('World!'); }, 1000);

-> errros. Not all javascript codes work on jsx & extendscript right? I wonder what are the rules to know which functions work and which don't?

I tried to check the docs and found: PAUSEGROWING

https://ppro-scripting.docsforadobe.dev/general/project.html?highlight=pause#project-pausegrowing

But I feel this is not it, not sure what or how to use it.

Is there any way to achieve what I want? Apply regular automated pauses during the code running?

Thanks
