Apps targeting Android 12 or later can't create fully custom notifications.

From the official documentation:

Note: Apps targeting Android 12 (API level 31) or later can't create fully custom notifications. Instead, the system applies a standard template nearly identical to the behavior of Notification.DecoratedCustomViewStyle.

So I think this is why I can't see notification layout on Android 14 emulator. It shows icon only. Do you have any plans to fix it?
