How can we use latest Screen Time API in swift & storyboard instead of swiftIUI ?

We are developing a mobile app where we have to restrict user's other app while joining our concert with their permission. We have gone through the power of screen time apis. It is possible by the Screen Time API latest update with individual authentication.

we have some query before move forward :-

  1. Can we implement Screen Time API in swift instead of swiftUI, as we seen this example shown in swiftUI https://developer.apple.com/videos/play/wwdc2022/110336/

  2. Is there any article related to this type of app ?

  3. Do we need to authorise individual user by FamilyControl first before manage restriction by ManageSettings ?

Can someone please suggest me ?
