Driving NavigationSplitView with something other than List?

Is it possible to drive NavigationSplitView navigation with a view in sidebar (left column) that is not a List? All examples that I have seen from this year only contain List in sidebar.

I ask this because I would like to have a more complex layout in sidebar (or first view on iOS) that contains a mix of elements, some of them non-interactive and not targeting navigation. Here’s what I would like to do:

import SwiftUI

struct Thing: Identifiable, Hashable {
    let id: UUID
    let name: String
}

struct ContentView: View {
    let things: [Thing]
    @State private var selectedThingId: UUID?
    
    var body: some View {
        NavigationSplitView {
            ScrollView(.vertical) {
                VStack {
                    ForEach(things) { thing in
                        Button("Thing: \(thing.name) \( selectedThingId == thing.id ? "selected" : "" )") {
                            selectedThingId = thing.id
                        }
                    }
                   SomeOtherViewHere()
                   Button("Navigate to something else") { selectedThingId = someSpecificId }
                }
            }
        } detail: {
            // ZStack is workaround for known SDK bug
            ZStack {
                if let selectedThingId {
                    Text("There is a thing ID: \(selectedThingId)")
                } else {
                    Text("There is no thing.")
                }
            }
        }
    }
}

This actually works as expected on iPadOS and macOS, but not iOS (iPhone). Tapping changes the selection as I see in the button label, but does not push anything to navigation stack, I remain stuck at home screen.
