BST/license in other devices

I've been a long time BTT user, and recently purchased BetterSnap tool as well due to the issue of snapping tool of BTT in Catalina (?!).
Anyway, my question is how I can install and use BST in other devices since I own multiple MacBook and/or MBP and I only installed it in one of my laptops.

Hi all,

I bought the BetterSnapTool few days ago but I want to install it multiple MacBook. Is there anyone successfully install BST in multiple machines?
