Run python window app in startx (x window)

I am running the python window app in startx, it works fine, but there is one issue. the issue will be in the next two images.\ -First image, Python app running in Linux GUI [window app in GUI](https://github.com/TarikVUT/Store-/blob/main/images/in%20GUI.png) \ -Second image, Python app running in Linux startx [window app in startx](https://github.com/TarikVUT/Store-/blob/main/images/In%20startx.png) As you can see the window app in startx is losing its frame. \ I have added the below code to **.xinitrc**

#!/bin/bash
#to set mouse cursor
xsetroot -cursor_name arrow
#to run startpython.py
exec python /home/GUI/startpython.py

What is the way to make the window in (startx) look like window in GUI (enable the frame around the window), without the frame I can close the window using (x). **Any idea?**
