How to add AutoSuggest to a settings input

Hi, I’m trying to add AutoSuggest that suggest note files, to an input field in my plugin Settings.

From my research I’ve seen it mentioned that I should use the class AbstractInputSuggest but I can’t find any resources about how to actually call/use this class.

I’d appreciate any insight, or alternative methods for adding AutoSuggest behavior. Thanks!

Searching GitHub to see how existing plugins use it is a good start, I think.
