Pls helppp i cant seem to open kvantum

i dont know how to open kvantum im on plasma 6 and ive alrdy copied this libsForQt5.qtstyleplugin-kvantum in my system pkgs or smt

libsForQt5 is ONLY for Qt5 packages. Plasma 6 uses Qt6 only. Instead, use kdePackages for all packages of that group. This prevents a lot of issues.

So in this case

kdePackages.qtstyleplugin-kvantum
