Sheet-like presentation on the side on iPad

Is there a way to get a sheet on the side over an interactive view with a proper glass background on iPad? Ideally, including being able to drag the sheet between medium/large-height sizes (like a sheet with presentationDetents on iPhone), similar to the Maps app:

I tried the NavigationSplitView like in the NavigationCookbook example. This is somewhat like it, but it's too narrow (sidebar-like) and doesn't get the full navigation bar:

I also played around with .sheet and .presentationDetents and the related modifiers, thinking I could make the sheet appear to the side; but no luck here. It seems to have all the correct behaviors, but it's always presented form-like in the center:

Example code for the sheet:

import SwiftUI
import MapKit
 
struct ContentView: View {
    var body: some View {
        Map()
            .sheet(isPresented: .constant(true)) {
                NavigationStack {
                    VStack {
                        Text("Hello")
                        
                        NavigationLink("Show Foo") {
                            Text("Foo")
                                .navigationTitle("Foo")
                                .containerBackground(Color.clear, for: .navigation)
                        }
                        
                    }
                }
                .presentationDetents([.medium, .large])
                .presentationBackgroundInteraction(.enabled)
            }
    }
}

I also tried placing the NavigationStack as an overlay and putting a .glassEffect behind it. From the first sight, this looks okay-ish on beta 3, but seems prone to tricky gotchas and edge cases around the glass effects and related transitions. Seems like not a good approach to me, building such navigational containers myself has been a way too big time-sink for me in the past...

Anyway, example code for the overlay approach:

import SwiftUI
import MapKit
 
struct ContentView: View {
    var body: some View {
        Map()
            .overlay(alignment: .topLeading) {
                NavigationStack {
                    VStack {
                        Text("Hello")

                        NavigationLink("Show Foo") {
                            ScrollView {
                                VStack {
                                    ForEach(1...30, id: \.self) { no in
                                        Button("Hello world") {}
                                            .buttonStyle(.bordered)
                                    }
                                }
                                .frame(maxWidth: .infinity)
                            }
                                .navigationTitle("Foo")
                                .containerBackground(Color.clear, for: .navigation)
                        }
                        
                    }
                    .containerBackground(Color.clear, for: .navigation)
                }
                .frame(width: 400)
                .frame(height: 600)
                .glassEffect(.regular, in: .rect(cornerRadius: 22))
                .padding()
            }
            
    }
}

Do I miss something here or is this not possible currently with built-in means of the SwiftUI API?
