The alternateIcon is a very cool feature that can make your user open up your app again if you change for something that the user may be interested.
For example, mother's day is coming and I would like to change to a mother's day themed app icon but I don't want to do it after the user clicks. Actually, I want to use this tool as a way to attract mothers that may see a change on her homescreen.
Doing it after the app opens makes the feature useless for us.
Our idea is to change the icon when the app is on background using a silent notification push that calls the
application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void)When I try to do this, I receive the following message:

Error Domain=NSCocoaErrorDomain Code=3072 "A operação foi cancelada."Is this a feature limitation, a bug or we did something wrong? Do we have another way do it?
