How can i send additionData.payload along with the notification for iOS and Android devices

[adiYaakov0105]

Trying to get payload addition data on android returns always null:

override fun onNotificationProcessing(receivedResult: OSNotificationReceivedResult): Boolean {
val id = receivedResult.payload.additionalData.getString("id")
val type = receivedResult.payload.additionalData.getInt("type")
val notification = PushNotification(PushNotificationType.valueOf(type), id)

    PushNotificationManager.onPushNotificationReceived(notification)
    return false
}
