I have purchased and downloaded the module.
From what I can see this is how you can embed and PDF from Google Drive into article.
1. Configure the module "What to Display" to PDF
2. Publish this to a module position
3. In article, use place module to embed this PDF into the article
4. If you want to embed other PDFs, you need to create a module for each PDF, and embed each module into the article
I am concerned that you need to create a module for each PDF/DOC/PDF/Excel.
Do you have a plugin that will do this directly in article editing?
