Show More Data for Own Watch App in Garmin Connect App

I have started programming a watch device app and have already recorded a session with it. The Garmin Connect app now shows the map for the activity (GPS) as well as the data for speed, heart rate, training effect, altitude, temperature and time in HR ranges.

I would like that it also displays more data like cadence or stride length. Is it possible to have these displayed without having to program a custom datafield?

In particular, is it possible to get the data of my HRM?
