How to retrieve backend base url into variable

Summary:

I am using usual approach of defining Backends at app or tenancy level and defining Service Connections based on the backends. The REST calls are working fine, but there is an additional requirement of hyperlinking transactions within the app based on the Backend base url.

E.g. I have a backend https://<****>.oraclecloud.com defined and I want to hyperlink https://<****>.oraclecloud.com/<yyy> into rendered data within the app.

While I can save the base url into a business object and fetch that into a variable for this hyperlinking but trying to avoid redundancy. Is there a way to fetch the base url from backend definition into a variable?
