Why does Apple Fitness not recognize third party app workouts as a workout?

I currently use the Ladder App and it integrates into Apple Fitness so that when I complete the workout in Ladder Apple Fitness automatically records that and it counts towards my exercise and move goals for the day. However it does not count as a "workout" towards badges. For example this week I have already completed 3 Ladder workouts. But Apple Fitness badges shows I have not completed any workouts towards the Perfect Week of Workouts badge. Is this the way it is supposed to be?
