File Size of Widget.js (440.9kb)

Using PageSpeed Insights to review and optimize my website » www.metals4uonline.com

The Yotpo customer reviews widget is 440.9 kb resource size, and makes up 82% of page loading time !!

Is there a way to minify it?? <https://staticw2.yotpo.com/XXXXXXXXXXXXXXXX/widget.js> (X replaces my ref #)

I’ve even opened the file, copied the text, then saved it locally to my server and modified the code to point to the local file “./js/widget.js” in hope to speed up loading and eliminate my largest HTTP Request of the entire website!
