How do I add new menu items?

[rmunoz33]

I feel a little silly asking for help, but I just can't seem to figure out how to add more items to the bubble menu in Novel for my Next.js app. The default menu looks like this:

And I would like it to look something like this:

Here is what I have in my code:

import { Editor } from "novel";
import { Extension } from "@tiptap/core";

const NovelEditor = () => {
  return (
    <Editor
      extensions={[
        Extension.create({
          name: "customMenu",

          menu: [
            {
              icon: "🤖",
              label: "Chat with AI",
            },
          ],
        }),
      ]}
    />
  );
};

Obviously, this menu option doesn't do anything. But I can't even get it to show up. What am I doing wrong? Any help you all can offer would be greatly appreciated. Thanks!
