Add links to non-native Steam games

[Luka8989]

I added all my games into steam to be able to emulate the PS5 controller in an Xbox controller as DS4Windows does not seem to work 100% with the PS5 controller, it emulates the controller but then it is not recognized inside the games anyway, now I would like to add the link of the games that I put in the steam library (the games are not all of steam), in Playnite without putting back logos, backgrounds, etc., what should I do?
