How to create iOS 15.x simulators in Xcode 15

I'm using Xcode 15.0 (15A240d) and I need to test some code on iOS 15. I'm unable to create a new iOS 15 simulator.

If I select the "Download more" option I'm presented with the "Platforms" tab in settings.

There's no option to actually select a platform here (which as you can see Xcode itself indicates I have on disk).

Neither double-click nor secondary-click do anything for me either. Am I doing something wrong or is this just bad design?
