Where do you enable the 'Request Authorization' button for the OPAG tool?

To enable the 'Request Authorization' button for the OPAG tool, the correct location is within the End-User UI settings, specifically under Dialogs and then the Application Block Notification section. This setting is crucial because it directly pertains to how users interact with the application when requests for elevated privileges need to be made.

When a user attempts to run an application that is blocked by the Endpoint Privilege Manager, the Application Block Notification dialog can present the 'Request Authorization' button, allowing users to request permission to run the application. This enhances user experience by facilitating smooth workflows while still maintaining a level of security and control over application access.

The other choices do not pertain specifically to enabling UI elements related to the application block notifications. For example, the Application Security Settings typically involve broader settings related to application permissions and security policies, while User Settings, Preferences might control general account settings rather than specific permissions for application access. Advanced Configuration, Policies would involve configurations that impact policies at a higher level, rather than the specific user interface elements that are presented to the end-user. Thus, the chosen answer is the most relevant to enabling user interaction specifically concerning application access requests.
