How do I pass data from an app delegate using UIApplicationDelegateAdaptor to a non-swiftUI class initialized in the same file?

Question

I have a top level app struct that loo

@main
struct GuardianApp: App {
    
    @UIApplicationDelegateAdaptor private var appDelegate: AppDelegate

    let accountStore = AccountManager()

    init() {
        appDelegate.registerForPushNotifications()
    }
    
  ...

When I register for push notifications and receive a device token (via didRegisterForRemoteNotificationsWithDeviceToken), I want to then call a method in AccountManager to use that token to register with my own server.

How do I properly make that connection? I do not

The app delegate class, for reference (which is successfully getting the token):

class AppDelegate: UIResponder, UIApplicationDelegate, ObservableObject {
    
    @Published var deviceToken: Data?
    
    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        self.deviceToken = deviceToken
    }
    ...
