Qt Location map plugins support only `osm`

There are many plugins that are not being built (and probably not tested) here
https://code.qt.io/cgit/qt/qtlocation.git/tree/src/plugins/geoservices?h=6.5.0&id=5278743537696d343633e771606a61b712573563

I have tried to build the mapbox plugin myself and although does build
It is not listed when calling:

qDebug() << QGeoServiceProvider::availableServiceProviders(); 

>>> QList("osm", "itemsoverlay")

There is nothing on it in https://doc.qt.io/qt-6/qtlocation-geoservices.html
