Child screen time in parent device

Hello, I developed a parental control app, this app has two clients one for the child and one for the parent. I could implement screen time to retrieve the child's screen time data and show it to the child by ActivityReportExtension but I didn't find any document to implement this feature on the parent device. I mean like the Apple screen time, parents can see their children's screen time (in the settings>screen time) I need to implement ActivityReportExtension in the parent client of my app that shows the child's screen time. is it possible or this API is only restricted to Apple itself?
