Launch app in Kiosk Mode

Hi, I am trying to build an app that allows user to use the tablet and with that, I want the app to launch in KIOSK mode preventing them from accessing the android apps or using the navigation buttons and pull down menu. So all they can do is use the app itself. Is there a way how to achive this?

And is it possibel to disable/exit kiosk mode using example by pressing volume down and power buttons...something like that.

Hopefully my question makes sense, thank you for the help in advance!

Not really an App Inventor Project to lock out all apps but one. Probably not possible using pinning with AI.
