Divi page builder not displaying on front end

I have Divi page builder enabled for popup maker. I am able to build my pop up using Divi, but when I open the pop up on the front end it doesn’t use the Divi styles at all. Here’s a screen recording video of what’s happening: https://cl.ly/475a97a56937

It seems like the divi styles are not being loaded when I open the pop up. The content is there, but it’s not formatted right. Is there something else I need to do to get it to load correctly?

Thanks!
