I've gotten Unity installed but confused now on where to put the LightWaveAppLink.unitypackage. Both 2019 & 2020 Wikis use info referring to LW 11.5, so I suspect some of the info might be out of date.

Anyway, the Wiki says to put the package file into a Editor/Standard Packages folder. I don't that folder under the Editor. I've: E:\Unity Hub\Editor\2019.3.15f1\Editor.

Where's the correct location?
