1 year ago I had success installing skins in ~/.var/app/com.valvesoftware.Steam/.local/share/Steam/skins/
I had to manually create the "skins" folder. But after I did that the skins I put in there became available to select in Steam.
I downloaded a skin from Steam Customizer and I'm not sure where the skins folder is. I've tried creating a skins folder in ~/.var/app/com.valvesoftware.Steam/data/Steam/ and ~/.var/app/com.valvesoftware.Steam/.steam/steam/ but neither seem to work. Does anyone know where the skins folder is for the flatpak version?
