REAL DOCUMENTATION, searching for the functions methods descriptions (coding)

I Found these 2 things:

- On the one hand, visual code the methods of a class like this:

- On the other hand, you have this kind of "very limited?" documentation:

https://ppro-scripting.docsforadobe.dev/other/time.html?highlight=time

It's missing most methods I am not wrong?

_

So I was wondering, where can I find descriptions of methods and attributes of different classes?

I found this: https://github.com/Adobe-CEP/Samples/blob/e60d6a22ef44d8eb4cca3904c35a0c050576b697/PProPanel/jsx/PremierePro.23.0.d.ts

But the class description is missing most methods seen on the screenshot above right?

So.. what is the best way to understand the functions?
