On a Samsung Android 12 users can 'hide' the Navigation bar by using gestures
Settings>Display>Navigation bar then select Swipe gesturers instead of the default Buttons
Recents or Overview To close the app one has to slide/swipe the app off the screen or use the Close all button. It requires two steps to close the app.

Why?
Becouse I am making an app for childrens and i want the children cant leave the app. my app is on education idea and thats why i want these parental control ( Just like kid space)
The easiest solution is to set your app app as home launcher temporarily. All buttons will be useless then. 
You can hide Status Bar with any of related extensions available.
This extension does not work on Android 12+. The APK cannot be installed there. In addition, only system apps are listed. To get it working you need to modify the Manifest.
I added your extension in project but I am unable to understand how I work with it.
If you can provide any example as my requirements so it will be helpful for me.
And also please update your extension as anke mam suggestion.
Thank you for your helping nature
