Hello I did create a new type of light for one of my projects, I just wanted to be fancy and set my class to the Lights group in the placement editor right here:

I tried using the UCLASS(ClassGroup specifier, but it does not work. so at the end I hard coded my class to be loaded using this code:

#if WITH_EDITOR
	IPlacementModeModule& PlacementModeModule = IPlacementModeModule::Get();
	FPlacementCategoryInfo Info = *PlacementModeModule.GetRegisteredPlacementCategory(FBuiltInPlacementCategories::Lights());

	
	FPlaceableItem* BPPlacement = new FPlaceableItem(
		*UActorFactory::StaticClass(),
		FAssetData(ARimLight::StaticClass(), true),
		FName("ClassThumbnail.RimLight"),
		TOptional<FLinearColor>(),
		TOptional<int32>(),
		NSLOCTEXT("PlacementMode", "Rim Light", "Rim Light")
	);

	IPlacementModeModule::Get().RegisterPlaceableItem(Info.UniqueHandle, MakeShareable(BPPlacement));
#endif

But obviously is not the right way to do that, I will like to know what is the right way, please if someone knows
