How to create a Plugin for PhAT?

Hey, I wondered how to create a toolbar plugin for PhAT in Unreal Engine 4.16.1.

I already created a LevelEditorPlugin like below this text.

For now I thought I have to replace the FLevelEditorModule with the FPhATModule but that class is in the private folder and has no header. I think it is a Plugin itself.
So how do I get the FPhATModule for adding toolbar extensions.

Thanks a lot.

void FGraspExtenderModule::StartupModule()
{
	// This code will execute after your module is loaded into memory; the exact timing is specified in the .uplugin file per-module
	
	FGraspExtenderStyle::Initialize();
	FGraspExtenderStyle::ReloadTextures();

	FGraspExtenderCommands::Register();
	
	PluginCommands = MakeShareable(new FUICommandList);

	PluginCommands->MapAction(
		FGraspExtenderCommands::Get().PluginAction,
		FExecuteAction::CreateRaw(this, &FGraspExtenderModule::PluginButtonClicked),
		FCanExecuteAction());
		
	FLevelEditorModule& LevelEditorModule = FModuleManager::LoadModuleChecked<FLevelEditorModule>("LevelEditor");
	
	
	{
		TSharedPtr<FExtender> MenuExtender = MakeShareable(new FExtender());
		MenuExtender->AddMenuExtension("WindowLayout", EExtensionHook::After, PluginCommands, FMenuExtensionDelegate::CreateRaw(this, &FGraspExtenderModule::AddMenuExtension));

		LevelEditorModule.GetMenuExtensibilityManager()->AddExtender(MenuExtender);
	}
	
	
	{
		TSharedPtr<FExtender> ToolbarExtender = MakeShareable(new FExtender);
		ToolbarExtender->AddToolBarExtension("Settings", EExtensionHook::After, PluginCommands, FToolBarExtensionDelegate::CreateRaw(this, &FGraspExtenderModule::AddToolbarExtension));
		
		LevelEditorModule.GetToolBarExtensibilityManager()->AddExtender(ToolbarExtender);
	}
}
