I would like to work on this issue!

[jai-dewani]

Sure,
Till now I have been using npm run build which does most of the job locally, so just running that on GitHub actions should work. Make sure that it runs it after every new push to only master branch because I do keep pushing coding to other branches time to time which doesn't requires the build process to be run again and again.
