How do I close a kivy application window with a button press?

Question

I am making a snake game in Python using Pygame and I want to add a Menu screen using the Kivy Framework. I have a "play" button in the center, and when I click it I want to close the kivy window but not Python Program as I want the game to run after you click the button.

I have already tried using app.stop() but that only clears the kivy window and and the windows sits there covering the screen.

Bind on_request_close to a function that calls Window.close() (among other exit scripts).

from kivy.app import App
from kivy.core.window import Window
from kivy.uix.gridlayout import GridLayout

class GameApp(App):
       
    def build(self):
        return MenuScreen()

class MenuScreen(GridLayout):

    def __init__(self, **kwargs):
        super(MenuScreen, self).__init__(**kwargs)   
        Window.bind(on_request_close=self.end_func)

    def end_func(self, *args):
        app.stop()
        Window.close()
