@Alicia Yes! Try updating --lb-radius and --lb-accent for example.

import { useThreads } from "@liveblocks/react";import { Thread } from "@liveblocks/react-ui";
function CommentThreads() {  const { threads } = useThreads();
  return (    <>      {threads.map((thread) => (        <Thread key={thread.id} thread={thread} className="thread" />      ))}    </>  );}
