Windows Button applet doesn't works in latte panel

Hello community, so i tried to install windows button applet (GitHub - psifidotos/applet-window-buttons: Plasma 5 applet in order to show window buttons in your panels) from widgets but it shows an error

file:///usr/share/plasma/plasmoids/org.kde.windowbuttons/contents/ui/main.qml:26:1: plugin cannot be loaded for module “org.kde.appletdecoration”: Cannot load library /usr/lib/qt/qml/org/kde/appletdecoration/ (/usr/lib/qt/qml/org/kde/appletdecoration/ undefined symbol: _ZNK12KDecoration223DecorationThemeMetaData9themeNameEv)

I am using Manjaro KDE with software specification as follow:
KDE Plasma Version: 5.23.5
KDE Frameworks Version: 5.90.0
QT Version: 5.15.2
Kernel Version: 5.10.98-1-MANJARO (64-bit)

Welcome to the forum!

Have you tried installing the applet from the repository? :arrow_down:

pamac install plasma5-applets-window-buttons

… or… :arrow_down:

sudo pacman -S plasma5-applets-window-buttons

I tried installing from both arch packages as well as AUR, didn’t works

Well, all I can say is that it does work for me. So the best I can do is ping the developer — he’s a member of this forum.
