Could you please just give quick example how to cancel the request with this setup?

[cqh963852]

import * as PIXI3D from "pixi3d/pixi7";

const controller = new AbortController();

const handler = setTimeout(() => {
  controller.abort();
}, 10000);

PIXI3D.glTFAsset
  .fromURL(
    "https://raw.githubusercontent.com/jnsmalm/pixi3d-sandbox/master/assets/teapot/teapot.gltf",
    {
      controller,
    }
  )
  .then(() => {
    clearTimeout(handler);
  });
