Beta access to Edge Functions

Hello, Seeking access to Edge Handlers. I requested access through the sign up form from address recently

Use Case:
We require Netlify’s edge handlers to change the content from a proxied site, part of our website is hosted in another server, and we want to change some lines of html code from the response before sending it to client. Things that we want to change are some html tags, and links in anchor tags. This should be done to make the proxy redirect work on every links on the part of site hosted in another server

Hoping to get a reply regarding the beta access / suitability of the above use case
