Can an iOS app share Screen Time goal progress with friends?

I'm developing an app that helps users reduce social media usage through friendly competitions.

With explicit permission, the app would track daily and weekly usage of selected apps like Instagram, TikTok, and YouTube.

Users could voluntarily share their live total usage, percentage improvement, or goal-completion status with approved friends.

Does Apple's Family Controls policy permit this? If not, is there an approved way to implement a friends leaderboard using Screen Time data?

Thank you!
