Notification is Only Triggering in the Lock Model in SwiftUI

Question

I am triggering Local Notification in my iOS app. I am getting the notification only when the device is locked. I want the notification to show on top of my app.

I am triggering notification with the following code:

struct ContentView: View {
   var body: some View {
   
        Button {
                    
           let content = UNMutableNotificationContent()
           content.title = "Cold Water Therapy"
           content.body = "Timer ended"
        
           content.sound = UNNotificationSound.init(named: UNNotificationSoundName(rawValue: "iphone_alarm_morning.mp3"))
        
           let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false)
        
           let request = UNNotificationRequest(identifier: UUID().uuidString, content: content, trigger: trigger)
         
           UNUserNotificationCenter.current().add(request)

          } label: {
               Text("Trigger notification")
          }
   }
}

I am getting the notification when the device is locked with the default sound.

How can I get notification on top of my app with UNNotificationSoundName(rawValue: "iphone_alarm_morning.mp3") sound?
