Copying Launchpad items to multiple computers

New Contributor II

We're looking into using Launchpad as a Launcher in a lab as an easy way for students to launch applications. We previously were using DragThing, which was perfect for our needs, but the developer is removing support for it. Unfortunately, I'm not able to find a way to copy and lock a customized Launchpad interface. The best I've found are old posts saying to copying db folders from ~/Library/Application Support/Dock, but the folders seem to have moved in Mojave.

Does anyone either have an alternative to DragThing/Launcher or know how to copy and lock a customized Launchpad UI?
