Hello dear developers,
I recently faced something, and it is steam games in my desktop. In my picom setting in picom config file, i set all windows to be transparented execpt of those that are in opacity-rules , and here is where i want to ask my question, how to set steam and all its games to be in opacity-rules in just one rule? I think it will became a problem in future for me if i add a game in my steam library, i have to add it in opacity-rules on config file.
`opacity-rule = [
#for Firefox
"98:class_g = 'firefox' && focused",
"70:class_g = 'firefox' && !focused",
#for Steam
"100:class_g = 'steam' && focused",
"95:class_g = 'steam' && !focused",
#for vlc
"100:class_g = 'vlc' && focused",
"99:class_g = 'vlc' && !focused",
#for FreeTube
"100:class_g = 'FreeTube' && focused",
"80:class_g = 'Freetube' && !focused",
#for Resident Evil 4
"100:class_g = 'steam_app_254700' && focused ",
"98:class_g = 'steam_app_254700' && !focused",
#for Dont Starve
"100:class_g = 'dontstarve_steam' && focused ",
"98:class_g = 'dontstarve_steam' && !focused",

];`
Here as you can see i added Dont starve & Resident Evil , i dont want to add each one of the games that i want to test or play.
could you give me some advise?
