Updating launcher directly
Adding a Game and a Mode
Adding the exe and bootstrapper to steam doesn't work for me, nothing wants to launch.
BUT opening lutris and adding the game to the aplication menu and then adding that to steam worked.
The only way for me to get LAN shortucts was to use the proton method on the later half of this guide, WaW works flawless, BO2 too but loading fast file mods crashes the game (even tho it didn't on my first time??), and black ops 1 doesn't even wanna start.
I can launch all the games via the pluto shortcut I made with the Proton method but the performance for bo1 sucks so I suggest sticking to the Lutris method for everyone else, it's easy to setup and it all works.
