Hello I have this function which I am calling from DIspatchSource Timer when App is in background and the timer is running for every 5 mins

     private func scheduleNotification() {
               NotificationManager.shared.removeAllPendingNotifications()
       let content = UNMutableNotificationContent()
    content.title = "######"
    content.body = "##### "
    content.sound = UNNotificationSound.default
    
    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
    let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
  
    UNUserNotificationCenter.current().add(request) { error in
        if let error = error {
            
            print("Error scheduling notification: (error)")
        }
    }
}

And The local Notification is not getting triggered sometimes. Can anyone please help with this issue .Is this expected or do I need to modify the qos level or anything.Any advice would be appreciated

I Have tried to dispatch from a global queue and increased the trigger Time but still no use
