What if the files in package to be patched are minified?

I was hoping to use patch-package to apply a small patch to swagger-ui since there is a fix that we need that nobody is getting around to merging. When I look at contents of node_modules/swagger-ui/, however, there are only minimized files in dist/ , so I'm not sure how I would patch that or whether it's even reasonable to try.

Is this a typical situation, or is swagger-ui breaking a norm by including only dist files?

Am I just missing some bit of common knowledge around this that could be added to the README for patch-package to help me and others who are missing that bit of knowledge?

Thanks for any help.
