Setting up react-create-app with ES

I am actually using I am using https://github.com/ayroblu/ssr-create-react-app-v2 which is based off react-create-app

Trying to use import and async/await in my server side code but unable to run build.

My build script uses "build": "react-scripts build",. Can I configure that script or do I need to replace the whole build script with something custom?
