Allow iOS shortcuts to control the Garmin Connect App

Having these shortcuts would allow us to control the App with Siri.  This would be FANTASTIC if we could also start and stop activities on the Vivosmart via the app.  Imagine be able to say "Siri, tell garmin to start a walk".  And you could have a winter walk started without needing to remove mitts, press and hold buttons on the Vivosmart, wait for it to get a GPS connection from the phone before starting.

If I have to get an apple watch for this would I ever go back to Garmin?
