How to open Apple's default app from the other app on Apple Watch?

Question

I have developed watchOS app that is only for Apple Watch not integration with iPhone app. From that need to open Apple's default app. such as :

• Map
• Setting
• Health
• HeartRate
• Sleep
• Workout

On iPhone we are open any app via URLScheme or open(url:), but how can we achieve same functionality on watchOS?

on iPhone :

let url = "abc.com"
if UIApplication.shared.canOpenURL(url) {
    UIApplication.shared.open(URL, options: nil) { (finished) in
            
    }
}

There is no equivalent on WatchKit. You can use openSystemURL(_:) to make a call or send a message, but You can't open another app.
