Debugging watchOS and iOS connectivity on simulator

In previous versions of Xcode you were able to pick a simulator pair (iOS + watchOS) when running a watch app. In Xcode 12, I cannot find the option for this.

In fact, the only way I seem to be able to test connectivity between my iOS and watchOS is to build and run the iOS app. Then on the simulator open the "Watch" app, navigate to my app name and enable the Show App on Apple Watch option.

This is clearly not a sustainable debug cycle.

How am I able to launch both apps from Xcode without jumping through the above hoops so that I can test the connectivity between the two apps?
