Can a DeviceActivityReport extension pass the user’s daily Screen Time total back to the main app

Hi,

I’m building an iOS self accountability app using FamilyControls and DeviceActivity. I can show the user’s real Screen Time correctly inside a DeviceActivityReport extension on a real device, but I want to use that same daily total inside the main app for today’s log and leaderboard.

What I’m stuck on is getting that value back into the app. I tried App Groups, shared UserDefaults, a shared file in the app group container, and CFPreferences, but the report still only works as a display and the main app never receives the total.

Is there any Apple supported way to use the daily Screen Time total from a DeviceActivityReport extension inside the containing app, or is this intentionally display only?

Thanks.
