Restrict visibility of Confidential AP Invoices in Oracle Payables

We have requirement to make payment to Employees who will be created as Vendors . Since these are confidential payments, we need to restrict visibility of such Invoices and payments to specific group of people.

Do you know if we can create a role to restrict the payments based on Invoice group , Invoice type , payment method, or routing attribute , etc?

Or is there any other suggestion on how such payments can be made in Payables?
