To use the menu component in your app, you can leverage the new SwiftUI integrations with AppKit. Here's a step-by-step guide based on the information from the WWDC session "What’s new in AppKit":

Create a SwiftUI Menu:

Define your menu using a SwiftUI view. You can use various SwiftUI views to describe the data relationship, such as toggles, pickers, and buttons.

Example:

import SwiftUI

struct MyMenu: View {
    var body: some View {
        Menu {
            Button("Action 1", action: { /* perform action 1 */ })
            Button("Action 2", action: { /* perform action 2 */ })
            Toggle("Toggle Option", isOn: $toggleState)
            Picker("Picker Option", selection: $selectedOption) {
                Text("Option 1").tag(1)
                Text("Option 2").tag(2)
            }
        } label: {
            Text("Menu")
        }
    }
}

Initialize an NSHostingMenu:
- Use NSHostingMenu to initialize the menu with the SwiftUI view you created.
- Example:
```
import AppKit
import SwiftUI

let myMenu = NSHostingMenu(rootView: MyMenu())
```
Use the Menu in AppKit Contexts:
- You can use this menu in any AppKit context that accepts an NSMenu, such as the new NSPopupButton initializer with a pull-down menu parameter.
- Example:
```
let popupButton = NSPopUpButton()
popupButton.menu = myMenu
```
