Thanks for updating in! The PDF Embedder plugin needs to be using a custom field so that you may be able to access using the ACF Pro plugin. I have checked the plugin and I doubt that it would do what you have in mind. The instructions for using the plugin are simply this:
To use the plugin, just embed PDFs in the same way as you would normally embed images in your posts/pages - but try with a PDF file instead.
From the post editor, click Add Media, and then drag-and-drop your PDF file into the media library. When you insert the PDF into your post, it will automatically embed using the plugin’s viewer.
You have to access the custom field name so that you can use it with ACF plugin. To better assist you with your issue, kindly provide us access to your site so that we can check your settings. Please create a secure note with the following info:
