How to restrict the Employee Data visibility in My Receipts page

Hello Everyone,

We need the Employee Data (Email and Phone no.) not to be visible with users when they search for "Requester" and "Entered By" fields by name.

Requester role would be given to all the users, so we don't want everyone getting access to the Employee Data (Email and Phone no.).

Please suggest how to achieve our requirement.

Screenshot for reference:

Also, what's the purpose of using Email and Phone no. details for Requester Name or Entered By search ?

Thank you,
