I'm trying to show a Badge number on my app when I send push notifications. According to https://api.playfab.com/documentation/Server/datatype/PlayFab.Server.Models/PlayFab.Server.Models.PushNotificationPackage there is a Badge property which I can set, but when I create a PushNotificationPackage, the 'Badge' property doesn't exist in the PlayFab ServerModel SDK. Am I doing something wrong? If not, how may I get the badge to show up on my iOS device?
