Plasmoids "Show Desktop" and "Trash" in KDE Linux

I always go to org.kde.plasma.showdesktop and org.kde.plasma.trash in /usr/share/plasma/plasmoids, and remove “-symbolic” suffix from the icon for these two plasmaoids after KDE Plasma installation, because I put them on a dock alongside “Icons-Only Task Manager”.
However, I couldn’t find them in that location in KDE Linux.
Any ideas what happened to these plasmoids???

This is confusing. I can confirm that they’re not present in that location, but they clearly exist and work just fine. I wonder where they are!

I can only see their binaries org.kde.plasma.showdesktop.so and org.kde.plasma.trash.so in /usr/lib/qt6/plugins/plasma/applets.
