How to show list of team members under a manager using org hierarchy

Hi,
We have created Manager dashboards which allows managers to access their engagement results and create action plans. Since there is always the issue of the HRIS list not being updated, managers are always asking us who are the members in their team. (We do not disclose who in their team have completed the survey). Is there any way by which we can display this using a widget or any other way?
Thanks in advance
