Viewer (user type)

A person who can only view a Data Studio file.

Viewers have Can View permission to the reports and data sources that have been shared with them. View permission allows you to interact with a report or view the data source structure, but not make any modifications. Viewers can share the report or data source with other people, but only with Can View permission. This can be prevented by Editors and Owners.
