Where can I read a list of Steam Play supported titles?

I'm using Steam on Linux. Settings shows an option 'Enable Steam Play for supported titles'. Where can I read a list of these games?

I found https://www.protondb.com/ which has compatibility information but doesn't distinguish officially supported titles from other titles.

Solution 1:

Here you go https://www.protondb.com/explore?page=0&selectedFilters=whitelisted&sort=playerCount

Also https://steamdb.info/app/891390/ which includes the precise Proton versions used for each game
