Duplicate Installation Script for Modifications for a new App/Game Version

Hello Everyone

I’m trying to get Affinity Photo2 to work and there’s an installation script for Photo 1 on the Lutris website. Can i somehow download it and try to modify it to make it work for Photo 2? That would make the whole work far easier as I might just have to add .net48 to the already existing script.

How could I download the script in case that’s possible and allowed?

Thanks for any help!
All the best,
