Trying to Integrate with Elementor

I am using Elementor Pro to create my website. I use it at work all the time to create websites for clients and love how easy it makes customizing things. But I’m now struggling to figure out how to properly integrate the Webcomic plugin for my webcomic site. I’ve read the the user guide, tried to follow it but it hasn’t worked. I’ve tried googling but can’t find info. I contacted Elementor support and they said I needed to talk to Webcomic plugin support. They said the problem was lack of a featured image to use for posts. I also tried shortcodes but will admit I haven’t worked with them so don’t know what I’m doing there. I’m really lost on what to do next. Looking forward to hearing from someone! Thanks!
