New to Monday - how to unzip and develop on a feature I've never worked on before

I’m trying to fix a feature in monday.com that was created by someone who previously worked on this project. I see that I can download a zip file but I’m struggling to find how to properly unzip the file so that I can then work on the feature locally.

Can someone point me to the correct documentation or help me with some steps on how I might be able to work on this feature?

You’re better looking in the git repository where the original author saved their work, as there’s probably a build step to turn the original code into whatever is in the zip file.

It seems that the original author didn’t save their work in our public repo (or they were developing locally, never pushed to an external space and therefore we no longer have access to their work). If I can figure out how to destructure the map files, will that still allow me to work on the super form we are trying to debug?
