Code Dictionary for VS code not apearing.

Although I have gotten the autocomplete to work for Unity, I would like to be able to see the code descriptions and what arguments can go with it. As a newcomer, I really need something to tell me what all of this stuff does. I’ve looked for some plugin that adds a code dictionary for unity, but the one I found was old and deprecated and, as far as I could tell, broken.
Thanks for any help you might be able to give.

I tried some more plugins, but I still not getting any code documentation. Would switching to Microsoft VS fix the issue?
