What determines which suggested apps are listed in Health?

Hello -

I'm wondering about the suggested apps listed by Apple in their Health app. For example, if you select the "Sleep" category there are a bunch of suggested apps like AutoSleep and Sleepzy. These are not Sleep apps that I installed on my own phone or ever shared sleep data with.

Is there a way to request to have a relevant app shown there? Or is it more automatic, like you're an app that integrates with HealthKit in certain ways and Apple has a way of determining that app is suitable for the user (ex. App Store popularity, user behavior, etc.)

What determines which suggested apps are listed in Health?
