If you update live activity with alertConfiguration: argument, iPhone shows a notification (or expands dynamic island): await runningActivity.update(content, alertConfiguration: .init(title: "Alert", body: "Done!", sound: .default)) Paired Watch presents a notification as well: I cannot find a way to dismiss that live activity notification from Watch. Is there a way to remove it similarly to UNUserNotifications? UNUserNotificationCenter.current().removeDeliveredNotifications(withIdentifiers: [notificationID])
