Hi all, new to Lutris (on the Steam Deck). When I installed a game from GOG it originally asked if I wanted to install extras. I didn’t at the time, but now want to. I have been searching but all I was getting was how to download Lutris or download/install the games.
How do I “go back” (as it were) and bring up the window that listed available extras to download?
Cheers 
I don’t think this is possible without uninstalling the game first, but it would be cool to be able to add/remove extras for each game after installation. I’d be interested in this, too.
Open GOG shop in any browser.
Extras may be downloaded from your account.
I don’t believe the OP is unaware of that… The question is obviously about how to do it from Lutris, and having it all at one place.
