### Back button handling
When the Emoji selector is shown, pressing back in the app closes it, intercepting any navigation events. This feature shows a way to integrate Compose and APIs from the Android Framework like [OnBackPressedDispatcherOwner](https://developer.android.com/reference/androidx/activity/OnBackPressedDispatcher) via [Ambients](https://developer.android.com/reference/kotlin/androidx/compose/Ambient). The implementation can be found in [ConversationUiState](app/src/main/java/com/example/compose/jetchat/conversation/BackHandler.kt).
