you should use your backend as a proxy for making requests to the Autodesk Tandem API, especially if you are encountering CORS issues in production. Here's why:

CORS issues arise because the Autodesk Tandem API does not allow requests from your frontend origin directly. You can bypass this by configuring your backend (Node.js with Express) to make requests to the Autodesk API on behalf of the frontend. This way, your backend handles the CORS issue because it will not be blocked by the browser.

• Set up a route in your backend that listens for requests from the frontend.
• From the backend, make the request to Autodesk's API.
• Return the response from Autodesk back to your frontend.
