Declaration
case missingNotificationFilteringEntitlementDiscussion
To call the reportNewIncomingVoIPPushPayload(_:completion:) method, a notification service extension must have a com.apple.developer.usernotifications.filtering entitlement. To apply for this entitlement, see https://developer.apple.com/contact/request/notification-service.
After you receive permission to use the entitlement, add com.apple.developer.usernotifications.filtering to the entitlements file for the Notification Service Extension target.
