At around 8:47 in the WWDC 2020 video "What's New in watchOS Design", in the example of a More button for the watch Camera app, a sheet is presented with a "robust set of options" which are rendered in a style somewhat similar to the iOS UITableViewStyle.insetGrouped / InsetGroupedListStyle. However, InsetGroupedListStyle isn't exposed on watchOS 7.
The closest analog I could see was when you embed a Picker into a List, the picker is rendered as a title/subtitle cell, and tapping on that cell presents a modal sheet with that one Picker's list of options in the same inset grouped style. However, this isn't an exact match - this picker has to be in a list, rather than a More button, and the picker only selects from one set of options, as opposed to multiple heterogeneous groups of options.
Can anyone provide guidance on how to render a sheet with multiple, heterogeneous groups of options, like the Camera app's More sheet, in this video?
