Thank you! It helped. And how to run ui tests (xcuitest) bundle using this flow?

Thanks! Your help is so much appreciated.

Thank you! I will try it in a little bit and then will come with the update!

Thank you for your help! A few days ago I found the actual answer which is “com.apple.clockface”. Hope it will be useful for some wonderers like myself :) Cheers

I am working on Apple Watch UI testing using XCUITest and I need to interact with the Home Screen itself for complication management (I know that for iOS it is "com.apple.springboard") and as well as with other apps in order just to launch them with XCUITest "launch" command.
