Function followEveryMessage

followEveryMessage<M extends IdentifiableMessage>(
opts?: ScrollToIndexOpts,
): OnMessagesCallback<M>
Performs a scroll to the bottom of the chat viewer when a new message is added. It returns a generic OnMessagesCallback that can be used with the chat viewer.

This function handles layout shifts that may occur after scrolling (e.g., when content like delimiters is rendered asynchronously). It monitors scrollSize changes and re-scrolls until the content stabilizes, ensuring the bottom remains visible.
Type Parameters
- M extends IdentifiableMessage
Parameters
- opts: ScrollToIndexOpts = DEFAULT_SCROLL_OPTS
  ScrollToItemOpts options for controlling the scroll behavior
Returns OnMessagesCallback<M>
A callback that performs the scroll action.
Example
```
<ChatViewer
  messages={messages}
  renderMessage={renderMessage}
  onNewerMessages={followEveryMessage({ smooth: true })}
/>
```
