I want to develop an app that collects a User's total iOS Screen Time using the Screen Time API. I know that this is possible in the most recent Screen Time API update (via the Device Activity Framework), but am unsure how to actually ask a Device for permission and then, once that permission is given, collect a User's total screen time. I've looked at the Documentation which provides sample code but do not have the proper background knowledge to understand it. How do I implement this code?
