Update: made some progress, since IOS 16 it seems possible to request individual screen time data from the api's. I am now using the com.apple.deviceactivityui.report-extension and com.apple.deviceactivity.monitor-extensio to get something working. However, still it only returns a view and I am looking for more raw data to do some calculations, challenges, etc. It should be possible as apps like Opal and Jomo do it but from all I can read iOS has restricted everything to return views. Or am I missing some newer API possibilities? Jomo also claims to do their own screen time calculation. Maybe they do something else I am not aware of. Any ideas still very welcom!
