HOWTO sync from Apple Watch to Garmin Connect

I am using Apple Watch to track steps and activities but would like to join a group of my friends who all use Garmin devices and Garmin Connect to share activity data. Is it at all possible to sync steps and activities tracked by Apple Watch to Garmin Connect?

I've checked on many places and tried using some 3rd party apps (MyFitnessPal) as well as Apple Health but it seems that Garmin Connect can only send activity data and receive nutrition data.
