In the view described in the following code, I would like to be able to select a marker, no matter if the marker is a Place or an Accommodation. Both Place and Accommodation are defined as classes with different fields. Both of them have latitude, and longitude. But I can only make one of them selectable depending on which one I put on this line

Map(position: $cameraPosition, selection: $selectedAccommodation) 

or

Map(position: $cameraPosition, selection: $selectedAccommodation) 

import SwiftUI
import MapKit

struct DestinationMapView: View {
    var destination: Destination
    @State private var cameraPosition: MapCameraPosition = .automatic
    @State private var selectedPlace: Place?
    @State private var selectedAccommodation: Accommodation?
    //@State private var selectedPlace: SelectablePlace?
    var body: some View {
        Map(position: $cameraPosition, selection: $selectedPlace) {
            ForEach(destination.accommodations ?? []) { accommodation in
                Group {
                    if let lat = accommodation.latitude, let lon = accommodation.longitude {
                        Marker(accommodation.name, systemImage: "bed.double.fill", coordinate: CLLocationCoordinate2D(latitude: lat, longitude: lon))
                            .tint(.blue)
                    }
                }
                .tag(accommodation)
            }
            ForEach(destination.places ?? []) { place in
                Group {
                    if let lat = place.latitude, let lon = place.longitude {
                        Marker(place.name, systemImage: place.placeType.systemImage, coordinate: CLLocationCoordinate2D(latitude: lat, longitude: lon))
                    }
                }
                .tag(place)
            }
        }
        .sheet(item: $selectedPlace) { selectedPlace in
            Text("Selected Place")
                .presentationDetents([.medium, .large])
                .presentationDragIndicator(.visible)
        }
        .sheet(item: $selectedAccommodation) { selectedAccommodation in
            Text("Selected Accommodation")
                .presentationDetents([.medium, .large])
                .presentationDragIndicator(.visible)
        }
        .onAppear {
            if let coordinateRegion = destination.coordinateRegion {
                cameraPosition = MapCameraPosition.region(coordinateRegion)
            }
        }
    }
}

How can add the capability to select the marker no matter if it’s of Place type or Accommodation type?
