My Game is running fullscreen,I want to add a button and Minimize the GameWindow when clicked it .
I know this in c++

UGameEngine* gameEngine = Cast<UGameEngine>(GEngine);
	if (gameEngine)
	{
		TSharedPtr<SWindow> windowPtr = gameEngine->GameViewportWindow.Pin();
		SWindow* window = windowPtr.Get();
		if (window)
		{
			window->Minimize();
		}
	}

But how to do this with BluePrint?
Thanks
