Who is responsible for enabling an information banner for users in ArcGIS Enterprise?

An administrator is responsible for enabling an information banner for users in ArcGIS Enterprise because this task typically involves managing system-wide settings and configurations that are reserved for individuals with administrative privileges. Administrators have the authority to configure the portal’s user experience, including features such as the information banner, which can display important announcements, notifications, or guidelines to users.

This capability is not accessible to regular members or general portal users, as they do not have the necessary permissions to make system-level changes. While any portal member can potentially view the banner once it is enabled, only administrators possess the rights to configure it. The option suggesting an action triggered by the system does not accurately describe the process, as enabling the banner requires deliberate input and setup from an administrator.
