Resolved: SwiftUI/macOS: DatePicker without background field

Question:

How do I get rid of the shaded background of the DatePicker field in macOS(!)?
.textFieldStyle or .background have no effect.
I tried this: Changing TextEditor background color in SwiftUI for macOS but seems to work only for TextField, TextEditor. Is there another NSView property that could be set?
        DatePicker("Start",
                   selection: $newDate,
                   displayedComponents: [.date])
            .datePickerStyle(.field)
//          .textFieldStyle(.plain)
//          .background(.clear)

Answer:

Here is a simplified demo of representable wrapper approach
Tested with Xcode 13.2 / macOS 12.1
enter image description here
struct DemoView: View {
    @State private var newDate: Date = Date()

    var body: some View {
        VStack {
            Text("Selected: \(newDate)")
            MyDatePicker(selection: $newDate)
        }
    }
}

struct MyDatePicker: NSViewRepresentable {
    @Binding var selection: Date

    func makeNSView(context: Context) -> NSDatePicker {
        let picker = NSDatePicker()
        picker.isBordered = false
        picker.datePickerStyle = .textField
        picker.action = #selector(Coordinator.onValueChange(_:))
        picker.target = context.coordinator
        return picker
    }

    func updateNSView(_ picker: NSDatePicker, context: Context) {
        picker.dateValue = selection
    }

    func makeCoordinator() -> Coordinator {
        Coordinator(owner: self)
    }

    class Coordinator: NSObject {
        private let owner: MyDatePicker
        init(owner: MyDatePicker) {
            self.owner = owner
        }

        @objc func onValueChange(_ sender: Any?) {
            if let picker = sender as? NSDatePicker {
                owner.selection = picker.dateValue
            }
        }
    }
}
