present a specific VC when local notification is tapped Swift - ios

Question

I tried to follow various solutions to the same problem in other posts but none seems to be applicable to my code.
I merged an alarm into my app and my goal is to get to NewMapViewControlleron user tapping on alarm local notification and call checkAlerts2() function which is not normally called when going to that VC via the app menu.
Thank you for you help as usual.
This is my AppDelegate:
import UIKit
import CoreData
import Foundation
import AudioToolbox
import AVFoundation
import Firebase
#UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate,AVAudioPlayerDelegate, AlarmApplicationDelegate {
var window: UIWindow?
var audioPlayer: AVAudioPlayer?
let alarmScheduler: AlarmSchedulerDelegate = Scheduler()
var alarmModel: Alarms = Alarms()
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
var error: NSError?
do {
try AVAudioSession.sharedInstance().setCategory(AVAudioSessionCategoryPlayback)
} catch let error1 as NSError{
error = error1
print("could not set session. err:\(error!.localizedDescription)")
}
do {
try AVAudioSession.sharedInstance().setActive(true)
} catch let error1 as NSError{
error = error1
print("could not active session. err:\(error!.localizedDescription)")
}
window?.tintColor = UIColor.blue
FirebaseApp.configure()
return true
}
