shared revision

Hello,

I like to make a shared revision since acrobat DC. My PDF document must be reviewed by several people who do not have Adobe account. In acrobat when I go TOOL / Send review, I can only gather comments via an internal server. I do not want people to download the document, but they do their online reviews. On paper Cloud, I have found that the ability to "COMPLETE AND SIGN" but I want there to have the best reviews.

Hoping to have been clear

thank you in advance
