Embedding Plugin Content Using Shortcode/Shortcoder

I’d like to embed a file download plugin inside of a multi-step form. The goal is to use an email address to access gated content which consists of almost 100 PDF files, categorized and tracked by user download. I’m unfamiliar with creating shortcodes, if this is possible, and/or how to do it if it is. The plugin is called WP File Download. I’ve attached screenshots of the app’s module, the inspector code, as well copy/pasted the HTML below. Please let me know your thoughts on the possibility and any help explaining the steps or links to documentation. Thank you!

Sample page using the plugin: https://boelte.com/trash-me/
