Need information about offer approver rights

Hi Team,

We have certain user types in Taleo through which users can approve the offers in Taleo like users having Genpact Hiring Team and Offer approver access can approve offers in Taleo. Can you please help me with exact permission name which is enabled through which we can identify that which user types can approve offers.

I need exact permission name which is checked by which users can approve offer.

Thanks,

Vimal
