[RMMV SCRIPTING] HOW DO MAKE INTELLISENSE IN VS CODE WORK FOR RMMV'S API?

Apparently there is a way to have Visual Studio Code (my preferred code editor) use Intellisense with RMMV's scripting API. However, I followed the instructions exactly, and it didn't work; the Intellisense only worked for stuff declared in my plugin file.


I'd like to know if perhaps there's something I'm missing, something that the tutorial doesn't mention. Help would be much appreciated.
