Insert stl file using C++ script.

[galaxyblazer]

There are many samples how to insert .stl or .obj file using Python or JavaScript script. But there are no any sample for C++.
I can't call addByInsert method from :
Ptr<Component> rootComp = design->rootComponent();
auto occ = rootComp->occurrences();
what next should be?
what I doing wrong ?

Here's the full code for a script that displays a dialog to get the filename of an stl or obj file and then inserts it into the active design.  To simplify the sample, there's almost no error handling.

extern "C" XI_EXPORT bool run(const char* context)
{
	app = Application::get();
	if (!app)
		return false;

	ui = app->userInterface();
	if (!ui)
		return false;

	Ptr<Design> des = app->activeProduct();

	Ptr<FileDialog> fileDialog = ui->createFileDialog();
	fileDialog->filter("Mesh Files (*.STL;*.OBJ);;All files (*.*)");
	if (fileDialog->showOpen() == adsk::core::DialogResults::DialogOK)
	{
		std::string filename = fileDialog->filename();

		Ptr<Component> root = des->rootComponent();
		Ptr<BaseFeature> base = root->features()->baseFeatures()->add();
		base->startEdit();
		Ptr<MeshBody> body = root->meshBodies()->add(filename, adsk::fusion::MeshUnits::CentimeterMeshUnit, base);
		base->finishEdit();
	}
	else
	{
		ui->messageBox("Canceled file dialog.");
	}

	return true;
}

Could you please send includes and using namespaces for this sample .
