what's new in imessage extension apps

The latest updates for iMessage extension apps were not specifically covered in the provided context. However, there are several new features and tools introduced at WWDC that could enhance the expressiveness and functionality of apps, including those that integrate with iMessage:

1. Genmoji: This new feature allows users to create custom emoji to match any moment. These custom emoji can be integrated into apps using the standard text systems with inline images.
