User Profile

In the wwdc2023-10043 session, the instructor adds a MapUserLocationButton towards the end, which seems to work fine in the SwiftUI Preview for him. However, when I follow this tutorial and add the very same button, I get a never-ending spinning wheel upon clicking it in SwiftUI Preview. I guess that the SwiftUI Preview cannot get a user location. I searched in various places whether I could set the user location, as possible in the simulator, but to no avail. In the Debug menu, there is a Simulate Location submenu, but it totally deactivated (greyed out). Does anyone know how to allow SwiftUI Preview to get an actual user location, i.e., either the one from my Mac or one that I could provide to the SwiftUI Preview simulator?
