I would like to get user's heart rate zones values in my watchOS app, is there any way to get it from HealthKit? Furthermore, is it possible to display the Apple heart rate zones widget in my watchOS app?

I have an iOS app compatible with WatchOS but I cannot get metrics specific to WatchOS in Analytics, I can only see results by following device types : iphone, ipad, desktop, appleTV, appleVision, ipod. Is there any way to get this information on App Store Connect?

I would like to get number of new users by month for my app. The description of "First Time Downloads" metric is : "The total number of first times an app is downloaded per Apple Account; Counted when an app is downloaded from the App Store after a user taps the "Buy" or "Get" button." https://developer.apple.com/help/app-store-connect/reference/app-metrics/ So, the first sentence says metric is per Apple account, so by Apple user. But the second sentence says metric is per device... My question is : does metric "First Time Downloads" get number of new users or new devices? if it is new devices, how can I retrieve number of new users (independently of opt-in or not)?
