Gui geometry not updating when using setter command

Geometry, Fields and Transportation
1

I am trying to define commands via the GenericMessenger clas and the commands are successfully being generated. But when I call the commands they do not update the geometry.

_Geant4 Version:_11.2.2
_Operating System:Ubuntu 24.04
_Compiler/Version:gcc 12.4
_CMake Version:3.28.3

Below are my setter functions to update the absorber thickness and material from example B4d

//....oooOO0OOooo........oooOO0OOooo........oooOO0OOooo........oooOO0OOooo......
void DetectorConstruction::SetMaterial(G4String matName)
{
  auto nistManager = G4NistManager::Instance();
  absoMaterial = matName;
  G4cout << absoMaterial << G4endl;
  nistManager->FindOrBuildMaterial(absoMaterial);
  DefineMaterials();
  DefineVolumes();
  G4RunManager::GetRunManager()->GeometryHasBeenModified();
  G4UImanager* UImanager = G4UImanager::GetUIpointer();
  if(UImanager->GetUIpointer()) {
      UImanager->ApplyCommand("/vis/viewer/rebuild");
  }
  
}

void DetectorConstruction::SetThickness(G4double abs_t)
{
  G4GeometryManager::GetInstance() -> OpenGeometry();

  //* example
  absoThickness = abs_t;
  G4cout << absoThickness << G4endl;
  DefineVolumes();
  G4RunManager::GetRunManager()->GeometryHasBeenModified();
  G4UImanager* UImanager = G4UImanager::GetUIpointer();
  if(UImanager->GetUIpointer()) {
      UImanager->ApplyCommand("/vis/viewer/rebuild");
  }
}

I am using the command

auto detConstruction = new B4d::DetectorConstruction();
runManager->SetUserInitialization(detConstruction);

in my main file to call the detector construction.

It may also be worth noting that I am printing out the values of the thickness and material in the definevolumes method and they are being realized by this class correctly based on the g4cout statement.
Any thoughts here?
