How do I approve a Knowledge Base article?

I have created a process definition to require manager approval on all external articles. Once the article goes from Draft to In Review I receive an email stating "XYZ has assigned a document to you for approval and publishing." But at this point I cannot find where it is so I can approve or reject.

If I open the article in the KB, I dont have those options to choose from (do I need to make them?)

If I open the documents module there is nothing assigned to me.

Please advise.

Thanks.
