Launch Apple Watch App Store from Apple Watch App

Is there a way to launch the Apple Watch App Store from an Apple Watch App?

Ideally, I want a "More Apps" button that users can tap to open the Apple Watch App Store with the list of my current apps.

I have tried using openSystemURL but I have no idea what the URL is for Apple Watch Apps, or even if this would work.

        let url = URL(string: "Apple Watch App Store URL")
        WKExtension.shared().openSystemURL(url!)

Any help is appreciated.

Cheers,

John
