Add a device auth before shutting down the device without unlock

hey guys I love Samsung products and I happen to have a Samsung Galaxy A10 smartphone where when I lock it, whenever I long press the power button and try to shut it down, it would require me to confirm ownership with a password or a pattern. I would really like to have access to the Android Java code the developers used to achieve this. Did you use a service, did you use a BroadcastReceiver, how do you detect the power shut down logo has been touched and then you intercept the system from shutting down until user proves identity, Thank You.

Hello,
As far as I know, the code you are asking for won’t be available publicly as it is Samsung’s proprietary information.
