I am working on a Gen1 V6 React Native application with AWS cli that utilizes Amplify with Cognito and the built-in UI for authentication that Amplify provides. Eventually will be including AWS Chime for Video Conferencing/Messaging functionality.

If I want to release to the mobile stores, how would I connect the frontend to my backend in Amplify? Do I need to also deploy my frontend to Amplify in order to do this or can I keep backend only in Amplify and frontend hosted on Google Playstore and Apple Store?

So far I have a dev, test and prod env setup in my Amplify backend and they all have Cognito through Amplify Auth and the UI that comes with it. I have associated branches in Github but I’m not sure if I need to link them to the backend resources from Github or if my application code can handle routing to the correct backend resources.
