Hello. I have built a site workflow that is tied to a library. Essentially its an annual review workflow. It took me a couple of weeks to get it to work at all. Now that it is working, I have now spent about 8 hours trying to get the notification email to link to the library item. I have read hundreds of posts and not a single person seems to have an answer.
you could query your library (maybe you're already doing in your workflow in order to get all the documents that need to be reviewed) and then collect also EncodedAbsoluteURL of files and use it in order to create link in notification email
