Done.

Add the widget:
  Right-click your panel or system tray -> "Add Widgets..." -> search
  "Synology NAS", or add it to the System Tray's configured entries.

Test it standalone (no panel needed):
  plasmawindowed $APPLET_ID

If the widget was already loaded, restart the shell to pick up changes:
  kquitapp6 plasmashell && kstart plasmashell >/dev/null 2>&1 &
