Related IE issues with razzle.js

On dev locally the error is here (IE can't read arrow functions)

And on dev server the error is here (arrow functions again...)

A way to fix this is replacing razzle.js with what we had before or something similar to what we had and implement either this https://github.com/andrewmclagan/react-env or https://www.freecodecamp.org/news/how-to-implement-runtime-environment-variables-with-create-react-app-docker-and-nginx-7f9d42a91d70/
