Here you go:
```sh
qtw=$(guix build qtwayland@6)/lib/qt6/plugins
QT_PLUGIN_PATH=$qtw QT_QPA_PLATFORM_PLUGIN_PATH=$qtw/platforms qutebrowser -s qt.force_platform wayland
```

Maybe a qutebrowser-wayland package variant should be defined to do the
required wrapping. Otherwise you can just install qtwayland@6 to your
profile and use ~/.guix-home/profile/lib/qt6/plugins in paths.
