Hello, I need guidance/feedback on how to run this jar file.

I tried running a .jar file using dockerfile on railway. This file contains two graphic/game libraries: LWJGL and libGDX.

The file itself is supposed to be headless however, as nothing launches(It's a seedfinder for a game, it was made by simply not launching a window of the game and instead forcing it to generate seeds internally)

You're supposed to interact with it through CLI commands
