Grabbing urls on a directory hidden by javascript

Little bit out of my wheelhouse because I have not run into this situation before where the tag is not in the code and neither is the url that each box on this page has, it appears to be generated once you click on one of them.

This is an example of a directory I was trying to scrape: https://ensun.io/search?q=RFID&locations=United%20States%2Cnull%2Cnull

When you click on one of the boxes, it goes to their specific profile page. I was hoping to scrape/crawl this website. I just don’t know how to achieve that.

Any ideas?
