I'm making a watchOS app, which has WKNotificationScene for dynamic notification, and button for open sms app. I've tried to open sms app via url with following orders, but I always get error below: Press Notification on watchOS, which is made of WKNotificationScene (a.k.a. dynamic notification) watchOS App comes to foreground. Press button, which executes WKApplication.openSystemURL(_:) to open SMS App Error occurs.

Does anyone know how to fix it?
