I’m having difficulty with the source code handed over by my colleague. This is an IOS webview application, using Kivy and the IOSWebiew class, everything seems to work fine, but there is an “X” appearing on the top left corner (it appears on all ios devices), how to hide it, thank you for your help

main.py

from kivy.app import App
from kivy.core.window import Window
import ios

Window.borderless = False
Window.fullscreen = False

class WebApp(App):

  def build(self):
    url = b"https://mywebapp.xyz/"

    self.height = 100

    if Window.width >= 2048:
      ios.IOSWebView().open(url, 0, 0 , 1030, 1360)

    elif Window.width >= 1668:
      ios.IOSWebView().open(url, -5, 0 , 850, 1160)  

    elif Window.width >= 1640:
      ios.IOSWebView().open(url, -5, 0 , 835, 1160)

    elif Window.width >= 1620:
      ios.IOSWebView().open(url, 0, 0 , 800, 1050)

    elif Window.width >= 1488:
      ios.IOSWebView().open(url, -3, 0 , 750, 1100)

    elif Window.width >= 1290:
      ios.IOSWebView().open(url, -5, 0, 440, 880)

    elif Window.width >= 1284:
      ios.IOSWebView().open(url, -5, 0 , 440, 880) 
    
    elif Window.width >= 1179:
      ios.IOSWebView().open(url, 0, 0 , 400, 830)
    
    elif Window.width >= 1170:
      ios.IOSWebView().open(url, 0, 0 , 393, 830) 
    
    elif Window.width >= 1125: 
      ios.IOSWebView().open(url, 0, 0 , 375, 810)
    
    elif Window.width >= 1080:
      ios.IOSWebView().open(url, 0, 0 , 380, 780)
    
    elif Window.width >= 828:
      ios.IOSWebView().open(url, 0, 0, 415, 810)
    
    elif Window.width >= 750:
      ios.IOSWebView().open(url, 0, -45 , 380, 830)

    else:
      ios.IOSWebView().open(url, 0, 0 , 380, 830) 

if __name__ == "__main__":
  WebApp().run()
