Rename 'Cancel' on modal sheet in SwiftUI

The Apple documentation gives some user interface design tips on modal sheets including renaming Cancel to something like Dismiss where relevant. But there's no guide whether this is possible in SwiftUI.

There's a link that takes you to setTitle for Watchkit: https://developer.apple.com/documentation/watchkit/wkinterfacecontroller/1619570-settitle

But is there something equivalent for SwiftUI on a Watch app?
