Renewal or unsubscription of orders by the manager or dedicated groups of people

We work on OIM 9.2. Assigned orders can be renewed or unsubscribed by the orderer and recipient. But not by the recipient's manager (Web Portal User Guide: You can unsubscribe your own products or those belonging to other identities that you manage). What needs to be configured so that the manager can also renew and unsubscribe?

For some products, it should be possible for dedicated groups of people to renew or cancel orders.
How can this requirement be met?
