Now I understand. I need to replace the custom conversation component with the proper one that uses use-stick-to-bottom. Let me update the files:

I've updated the conversation component to use the use-stick-to-bottom library as you provided. The key changes are:

1. Conversation component now wraps StickToBottom with initial="instant" so messages scroll to bottom immediately on load
2. ConversationScrollButton added to show a scroll-to-bottom button when user scrolls up
3. ChatContent uses useStickToBottomContext() hook to access scroll functionality, which automatically sticks to the bottom as new messages arrive

The issue is that the initial="instant" prop on the Conversation component should handle instant scroll, but the messages are being set in a useEffect which happens after initial render. I need to ensure the scroll happens after the messages are actually rendered. Let me fix this:

I changed the approach to use initialMessages directly in useChat instead of setting messages in a useEffect, and added a requestAnimationFrame wrapper to ensure the DOM has updated before scrolling. The scrollToBottom("instant") call with the "instant" argument should now immediately jump to the bottom without any animation on initial load.
