Is possible to insert other glb on WebXR ar-mode?

[GiovanniTurri]

Description

On examples like https://immersive-web.github.io/webxr-samples/immersive-ar-session.html or https://immersive-web.github.io/webxr-samples/hit-test.html is possible to add additional models using something like:
let model = new Gltf2Node({url: 'media/gltf/model.gltf'}); arObject.addNode(model);

I tried to integrate the two examples by WebXR using the scene Symbol (as found in other issues here), but had no results when opening the model-viewer in ar-modes="xrweb".

I used
const modelViewer = document.querySelector('model-viewer'); const $scene = Object.getOwnPropertySymbols(modelViewer) .filter(symbol => symbol.description === 'scene')[0]; const scene = modelViewer[$scene]; // is a Three.js Scene instance that contains the model

Is it impossible to use those WebXR examples (that integrate ThreeJS) or is my code strategy not right?
Do you have suggestions?

Thank you

The whole point of our library is so that you don't have to know about or touch anything related to WebXR or three.js; it all just already works with a declarative HTML element. If you want to go to a deeper level, you should probably be using three.js directly intead of model-viewer. What are you trying to accomplish?

Ok, thank you so much!
Yes I thought only that it could be compatible but a stand-alone solution (so out of ) is the only way to display in AR more than one model
