Ability to start a workout on Apple Watch

[audrastafursky]

Hello! I am working on a project where the iOS app is written in React Native, using this library to log health activity. I want to be able to start a workout on my phone, and have the associated WatchOS app launch and start the workout. The workout video player would be able to start, stop, and pause the Watch app.

I would love to start building this feature if you all agree it would be a good fit for this library. Thoughts on how to make this happen?
