Webflow site within reverse proxy configuration

Hello,

We are trying to use our webflow site a custom domain. The planned setup is shown below:

With the current capabilities of domain connection on webflow,
we need to insert a CNAME record to our DNS records.
Is there any other way around that we can use here to achieve this?

What we tried so far;

  1. Exporting webflow to another s3 bucket

While this works fine, it contradicts our purpose of using webflow in the first place.

  1. Using Cloudfront to distribute the requests

This did not work as the CNAME value is proxy-ssl.webflow.com.

Thanks in advance.
