start apple watch app from iPhone app

we have an app for apple watch paired with the iphone app. We would like the watch app starts running when the iphone app is opened. Is there a way to activate the watch app from the phone app programatically? We have seen that Nike run club app works this way but not sure this is available for other apps as well.

There should be a way to do so as Hole19 can do this too
yes, I found it, you can use startWatchAppWithWorkoutConfiguration and I tested for my app. However, there is a concern on this:
