Implementing service workers using workbox library in project using modular

[RaviTewari1]

My project uses modular for build. I want to implement service workers using workbox library in my project. However, I need to probably change the webpack configuration to generate service worker file at build time but modular does not expose the webpack config file. How can I do it? Also, I tried using react-app-rewired to extend the webpack config but it is giving an error as it cannot find react-scripts folder
