There is only one option on this page:

Next there is a tree style view of the access controls for your wallets.

Click with the left mouse button on the > symbol beside a wallet name to expand the tree. You will see the name of each application that has asked for access to the wallet, and the policy you set for it. You cannot edit policies here, or add them, but it is possible to delete an entry by right mouse button clicking on it and choosing Delete from the context menu that appears, or by simply selecting it and pressing the Del key.

An application that has been allowed access to a wallet is granted access to all passwords stored inside.
