Does a user require any specific privilege to delegate Requisition document to other user?

Summary:

Suppose there is a user A. When we log in with user A and try to search for other users to delegate the requisition document, those users do not appear in the search list of values (LOV). This user A doesnt have an employee role. However, user A has the "Manage Delegation Approvals" privilege.

Despite this, when searching for the users, their records do not appear in the search results.

What could be the possible reason for this?
