The client services and customer support teams share the same profile but have different permission...

When users share the same profile but require different user interface experiences, Component Visibility is the most effective tool. In the Lightning App Builder, the administrator can select the "Related List" component (or a "Related List - Single" component for Retention) and add a visibility filter. The filter can be set to "User > Permission > Custom Permission" or "User > Profile," but since they share a profile, the best approach is to filter based on a Permission Set or a specific user field. This allows the Retention list to be visible only to the Client Services team members while remaining hidden for the Customer Support team, even though they are looking at the same record. Page Layout Assignment (Option A) and Record Type Assignment (Option C) are profile-based and would not work since the teams share a profile. Sharing Settings (Option D) control access to the data itself, but the request specifically asks to hide the UI element (the related list).
