open google chrome in fullscreen by default

I have a website that I always need to open in full screen and ban the exit from the full screen. Also, you need to hide the cross button in the circle that goes out of the full screen. I tried to make a kiosk in the google app builder but it keeps the buttons open - it's not good. Please, help))
