Hi Ernest. I understand overall, but I’m not technical enough to answer your method/API questions. I also had filled out a ticket with Dudaster, the developer that makes this plugin, but its a GitHub forum and nobody has responded so far.
I could provide you with a login to our website, and or links to the plugin’s support or anything you would need to help me figure this out and I do not mind paying you a fee for this, whether it is hourly or whatnot.
Elementor has no way to customize the post type loop and unfortunately we had to use a 3rd party plugin like Ele Custom Skin for this. It reallly should be an Elementor feature out of the box and hoping they add it soon.
Please let me know what you need, any and all help truly appreciated. Thank you again!
