Hello I'm developing watch app i tried to customize long look notification view but encounter some problem. When i configure sashColor of WKUserNotificationInterfaceController in WatchOS9. it seems not effect color of sash and looks system default translucent color. But custom sash color of long look notification looks well under WatchOS9 I couldn't find any document or comment about sashColor property is deprecated on WatchOS9. Please give me a advice

I recently moved my watch app from InterfaceController to the SwiftUI LifeCycle, but I've encountered some issues. In my app, I'm using group notifications. Before I moved to the SwiftUI LifeCycle, when I received a group notification with the same thread identifier, it appeared as a stack in the notification center of the watch. When I touched the stack, it extended with individual notifications. However, after moving to the SwiftUI LifeCycle, when I touch the stack, it only shows the first notification of the stack and doesn't display the extended notifications. Do I need a custom group notification view in the SwiftUI LifeCycle, similar to the Message App? Is there any other way to use the previous static group notification view? Please help me!
