How do I programmatically close an Editor Utility Widget?

So, I’m creating an Editor Utility Widget Wizard to help people create a required asset for my plugin. (It manages some of the code’s inner workings, depending on settings.)

The problem is, I want to have a “Quit” button, but I can’t seem to make the EUW close it’s window. Does anyone know how to, on a button press, stop, close, or quit a running editor utility widget?

I’d like to do this in blueprints, but can also execute c++ code if needed.
