How to access current node in onUpdate method?

[seleckis]

I'm extending Table:

import TTTable from "@tiptap/extension-table";
import { Node } from "@tiptap/pm/model";

export const Table = TTTable.extend({
  addNodeView() {
    return ({ node }) => {
      // node is available here
      const dom = document.createElement("table");
      const contentDOM = dom.appendChild(document.createElement("tbody"));

      dom.append(contentDOM);

      return {
        dom,
        contentDOM,
      };
    };
  },
  onUpdate() {
    // I need node here
  },
});
