How can I show product version (azure app setting) from React Front End

I am developing an app which is a web api with a front end. So, I have 2 azure webapps each one has a different version number app setting.

Using azure devops build pipelines; I am updating an app setting with the version number for each of these webapps.

From the frontend which is react, how can I read the app settings version variable; so that testers and users can know exactly in which version they are working on.

Maybe I am thinking it in the wrong way?
