Specific Android and ios code for app development

We need someone to write us a code that would give our app access from the lock screen of the phone, same as how some of the default apps such as calculator, camera, flashlight etc. have so the user without unlocking the phone can access the app. This code should be written in a way that would bypass the authentication process which comes before opening an app from notification or by the general entry process, and let the phone run the app in full function and full access to both internet and all internal properties such as storage, microphone, camera etc. Also, the code should designate an icon holder place in the drop down/up menu notification bar of the android and control center of the ios beside the other apps such as camera, calculator, WiFi on/off, Bluetooth and other usual icons are. The code should be testable on any app you suggest as an example. It also can be a dummy app with some permissions and accesses to examine the functionality. It would not be on our current app until it has been tested on some other app. Thank You,
