Set Kiosk mode in Chrome for Android

I'm trying to set the --kiosk and the --kiosk-printing flags in Chrome for Android on my Galaxy Tab 10.1. All the instructions that I can find here and elsewhere tell me to go to chrome://flags and set the flag there. But neither of these flags is mentioned in the list there. What do I need to do to set kiosk mode? I'm using Chrome 39.0.2171.56 on Android 4.0.4
