Hi,Currenlty our project are integrating the func for `Add to siri`, we need to handle the callback from the shortcut controller inside the delegate ofINUIEditVoiceShortcutViewControllerDelegate & INUIAddVoiceShortcutViewControllerDelegate, we can see in the method func addVoiceShortcutViewController(_ controller: INUIAddVoiceShortcutViewController, didFinishWith voiceShortcut: INVoiceShortcut?, error: Error?)andfunc editVoiceShortcutViewController(_ controller: INUIEditVoiceShortcutViewController, didUpdate voiceShortcut: INVoiceShortcut?, error: Error?)We can see there can be error return, however, we don't know what kind of error will be return after searching the documents.Could anyone help on clarifying this? Thanks a lot.
