Dear professor:
I try to using the vecgeom to navigate the transportion of particle but i could not find the class: G4VecGeomNavigator , the code only include the TG4VecGeomNavigator.h
// make the G4VecGeomNavigator
auto nav = new G4VecGeomNavigator(g4geometry);
// hooking the navigator into G4
auto trMgr = G4TransportationManager::GetTransportationManager();
trMgr->SetNavigatorForTracking(nav)
