Create different Session Groups and based on the Role be able to only see those sessions part of that group
You can achieve this through Roles and Permissions. On the Security Tab of the Administration page, you can edit a role's ability to view certain session groups. When editing a role, click on the specific session group to configure permissions, including ViewSessionGroup, JoinSession, and RunCommandOutsideSession. Here's also a list of role-based security permissions for your references.
