notification.contentIntent?.send()

it is not working when i set targetSdk=34 .
Notification is got from Notification Listener Service by fetching other apps notifications. to get notification from other app is below as:

class NotificationListenService : NotificationListenerService() {
   override fun onCreate() {
        super.onCreate()
}
override fun onNotificationRemoved(sbn: StatusBarNotification) {
        super.onNotificationRemoved(sbn)
    }

    override fun onNotificationPosted(sbn: StatusBarNotification) {
        super.onNotificationPosted(sbn)
         notification=sbn.notification
    }

}

I want to open that specific app with a specific screen pending intent, like if I have WhatsApp notification pending intent, then open the details messages screen of a user who sent that notification on calling.
