 Our SDK relies on the default caching provided by React Native (avatars, image attachments, URL preview, etc.).
 This default solution is far from perfect, and you might see a lot of images missing while operating the app in offline mode.
 We provide a convenient solution to replace all the underlying usage of the [`Image`](https://reactnative.dev/docs/next/image) component using the `ImageComponent` prop on the `Chat` component.
