Mobile performance significantly lowered by 2 .js files under app/dist/

Could anyone help identify who’s responsible for these .js files? They’re identified as unused for mobile page performance and I want to turn them off (since they’re under “app” I assume there’s a way)

cloudfront.net/app/dist/app-3.0.0.js

cloudfront.net/app/dist/vendor.js?v=3.0.0

Thanks!
