How to get to it
Through a button on the main screen or a text on the time out popup.
The text input
Here, you must repeat the confirmation text to prolong time with no additional spaces or dots. The text can be changed in settings.
The ok button
Submits the phrase. You won't see it until the phrase is exactly same as the confirmation text to prolong time. If you pass, you get to the screen unlocked popup.
The X button
Clicking it returns you to the app or time out popup, depending on where you opened it from. Use it when you decide that you don't know what you are doing and don't have a reason to do it.
