Hello, This plugin is packaged as a part of qtwayland, and `guix shell --pure --preserve="^(XDG_|WAYLAND_DISPLAY)" bash pcmanfm-qt qtwayland -- bash -c "QT_QPA_PLATFORM=wayland pcmanfm-qt"` does work as expected (whereas it does not if I leave out qtwayland). You might want to install qtwayland in your profile for it to work.
Best, Josselin Poiret
