• general comments: click on the right-side bar + button, you will be able to add a general comment for the document.
• localized comments: just click where you want to comment, a new comment will pop up at the exact position on the document

To review / approve / reject a document, click on the appropriate button on the post from the Coment app that follows the upload of a document.

The App has only access to the document you share with it.
