How to open project from my library on linux

Goal: Open “Action RPG” and “Strategy Game” both free samples from legacy on linux. Or even anything from my library.

Tried: A) Download lutris and use unreal engine from there where it shows my library. But from lutris, unreal engine open as a blank screen. B) Downloaded unreal engine 5 stand alone. That works. The sample projects open, but I’m unable to figure out how to download samples from my library like the bigger games such as rpg, strategy, etc.

Any help would be appreciated because I’m lost.
