javascript not updating

Hello,
I made a change in ultimate member plugin js file “um-scripts.js”. and it works fine if the option for minified js is disabled. but if I enable this option from backend then only um.min.js file is called in frontend and my changes are not showning there.

so my question is that how I am able to reflect back my changes into um.min.js file to make my code run successfully in minified form of js also.

thanks in advance
