Bug 476389 is about the plasmoid/tray icon not appearing at all in Plasma 6, this one is about the plasmoid not having an option/button to open the app (the `kdeconnect-app` executable, which has some additional features not available in the plasmoid) instead of just the KCM/settings window, which is still the case for now.
