What is the primary function of the 'Viewer' role in ArcGIS Online?

The primary function of the 'Viewer' role in ArcGIS Online is to allow users to view and interact with shared content. This role is designed for individuals who need access to geospatial data and maps but do not require permissions to create, edit, or manage content. Viewers can explore web maps, applications, and other shared items, which enables them to analyze and utilize the available information without the capability to alter it.

This role supports collaboration and sharing within an organization, as it ensures that users can access important resources while maintaining control over data integrity. By limiting permissions to viewing and interacting with content, the 'Viewer' role helps to manage user interaction in a way that prioritizes secure and responsible data use.
