The „review list“ will appear on the right when you log in as a user with the „review role“ and there are items to review, in this case, you need to review the test document. Click the document to open the item. At this point, you essentially have the following choices for this item:

Reject it: Reject it by selecting Reject from the drop-down choices. This will move the content back into the visible state and assumes that as a reviewer you‘re unhappy with it. Usually you may want to click the Advanced option to open the comments form and add some comments stating why you‘re rejecting it.

Approve it: Approve it by selecting Publish; this will change the content into the published state. This will make the content publicly available.

Do nothing: Leave it by doing nothing. This leaves the content in limbo. You need to return to take further measures, because it‘ll continue to show up in your list of items until you make one of the previous actions.

Edit it:  Edit it, and then perform one of the previous actions. As the reviewer, you can make any change you‘d like to do, so feel free to change the content by using the edit tab.

Once you‘ve moved content out of the review state by publishing or retracting it, it will no longer show up in the review list. Of course, this assumes you do have someone as a reviewer for your site; this usually (although not necessarily) is also the user who created the Plone site as an administrator.
