How to override copy behavior (plain text)

Hi, I have the following Tiptap extension (node):

export const MathConcept = Node.create({
  name: "mathConcept",
  inline: true,
  group: "inline",
  selectable: true,
  draggable: true,

  addAttributes: () => {
    return {
      name: {
        default: null,
        parseHTML: (element) => element.dataset.name,
        renderHTML: (attrs) => ({ "data-name": attrs.name }),
      },
      id: {
        default: null,
        parseHTML: (element) => element.dataset.id,
        renderHTML: (attrs) => ({ "data-id": attrs.id }),
      },
      description: {
        default: null,
        rendered: false,
      },
      "original-name": {
        default: null,
        rendered: false,
      },
      "concept-type": {
        default: null,
        parseHTML: (element) => element.getAttribute("data-concept-type"),
        renderHTML: (attrs) => ({ "data-concept-type": attrs["concept-type"] }),
      },
    };
  },

  renderHTML({ HTMLAttributes, node }) {
    const attrs = mergeAttributes(HTMLAttributes, this.options.HTMLAttributes, {
      "data-type": this.name,
    });
    return ["span", attrs, node.attrs.name];
  },

  parseHTML() {
    return [
      { tag: `span[data-type="${this.name}"]` },
      /* Parse RichMention */
      { tag: `div[data-type="${this.name}"]` },
    ];
  },

  addNodeView() {
    return ReactNodeViewRenderer(MathConceptNodeView, {
      attrs: {
        "data-copyable": "true",
      },
      stopEvent() {
        return false;
      },
    });
  },

  addProseMirrorPlugins() {
    return [
      suggestion({ editor: this.editor, ...MathConceptSuggestion }),
    ];
  },
});

And the problem is that when I copy it and paste in my tiptap editor then it works and its correctly parsed into that node, but when I copy it to chat gpt, the empty string is pasted instead of node.attrs.name. I checked the clipboard text and html and the result for html is:

<p data-copyable="true" style="margin-left: 0px!important;" data-pm-slice="0 0 []"><span data-name="Postać kanoniczna funkcji kwadratowej" data-id="ffd192bc-b987-4b88-885f-233471f1efd6" data-concept-type="DEFINITION" data-type="mathConcept">Postać kanoniczna funkcji kwadratowej</span> </p>

while as I said, text/plain is an empty string. How can I fix that? Can I somehow override the way this node is serialized when copying it? Without overriding the html part?
