Where to find downloaded landscape wallpapers?

I have downloaded few landscape wallpaper but I am not able to find those wallpapers at the location ~/macintoshHD/Library/ApplicationSupport/com.apple.idleassetsd/customer/4KSDR240FPS

I am using macbook pro and tahoe version26.

Can someone let me know what's going wrong and how can I fix it or where can I find it?
