How to Reboot real Android device

Installed Application(.apk) on real Android device, after some verifications I have to restart my Device I didn’t see any Katalon(I am using Katalon 7.8.0 version) Keywords to restart device.

Once device restarted I have to check my previous actions still stored not removed from my application cache.

Please help me to solve this issue.

Thanks in advance,
Chandra
