Where do I find LifeSaver’s “Passenger Unlock” and “Emergency Unlock” on iPhones?

“Passenger Unlock” and “Emergency Unlock” are found in LifeSaver’s lock screen. This lock screen appears when LifeSaver detects a drive, and on iPhones, it can be brought up by the following ways:

1. Start drive with LifeSaver’s homepage (blue screen with 5 icons) on foreground: LifeSaver’s homepage will change to the lock screen that has both of the unlock options.
2. Start drive on iPhone’s homepage or any app other than LifeSaver: a banner saying “Keep your eyes on the road” will pop down from top of the screen once LifeSaver detects the drive. Touching the banner will open LifeSaver’s lock screen that has both of the unlock options.
