Sending a push notification to iOS through a CLI function - ios

Question

I am attempting to use a CLI function to send a push notification to both android and iOS devices. When I use the iOS version, no notification is received when sent from my function. However, when I send them from the Firebase console, it will receive the notification but only while the application is open. I am thinking I am missing either one or more crucial steps in setup or my function does not have all the needed data in the payload.
My function is sending as follows:
return Promise.all([token]).then(result=>{
const payload = {
notification: {
title : likename + " liked your post!",
"priority" : "high"
}
};
console.log(token);
return admin.messaging().sendToDevice(token,payload);
});
I have my iOS application set up with a certificate and have implemented my APP delegate as follows:
import UIKit
import Flutter
#UIApplicationMain
#objc class AppDelegate: FlutterAppDelegate {
override func application(
_ application: UIApplication,
didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
) -> Bool {
if #available(iOS 10.0, *) {
// For iOS 10 display notification (sent via APNS)
UNUserNotificationCenter.current().delegate = self
let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
UNUserNotificationCenter.current().requestAuthorization(
options: authOptions,
completionHandler: {_, _ in })
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
GeneratedPluginRegistrant.register(with: self)
return super.application(application, didFinishLaunchingWithOptions: launchOptions)
}
}
Any help is greatly appreciated and please let me know if you need additional information.

After hours of reflection, I realized I had only implemented code to respond to the onLaunch or onResume versions. I had to implement those methods to my code and now have success.
