Implement Realtime Autofetch on Config Update Notifications #9206

Samruddhi90 · 2025-08-13T09:26:07Z

This PR is a follow-up to #9202.

This PR adds logic to listen for realtime update notifications. When a new template version is detected, it automatically fetches the config. After a successful fetch, a callback is triggered to notify the app that a new config version has been retrieved and is ready to be activated.

Next PR will include test cases for all the functionalities.

…Logic
