24D Transaction review and control approval worklist

Today we were testing new functionality for 24D. The feature Transaction review and control for receivables is a nice feature. The only thing is when setting up this functionality we don't get a notification in our worklist? In the documentation I only see you can navigate via Manage Transactions. How do approvers know which invoices need attention from them? If there are multiple approvers how do they know which invoice to approve? Or am I missing something in the setup?

And is there a way to withdraw transactions from the review?
