How to hide employees information from the users of the organization?

As per my understanding, within Zoho People, we have users, i.e., team members, who need access to the portal, and then we have employees, i.e., those team members (Blue-Collar workers, etc.) who do not need access to the portal.

We want to set the restrictions so that the users cannot view any information about the employees, i.e., blue-collar workers of our org, except for the HR and the admin.

Is this possible? If so, could someone point me in the right direction?
Thank you!
