How do I display the manager's person number on the Public Info page?

Content (please ensure you mask any confidential information):

Our client wants to display the manager's person number next to their name on the Public Info page under the Managers and Directs section (screenshot below). I know typically this can be done using Page Composer but when I try to do that, it displays the employee's person number, not their manager's. Does anyone know how to accomplish this?

Thank you!
