Which access permission would you provide to a coworker to collaborate with them on a report?

To collaborate on a report in Data Studio (now Looker Studio), you need to grant your coworker "Can edit report" access. This permission allows them to make changes to the report's layout, visualizations, and settings, enabling true collaborative development. "Can view report" would only allow them to see the report without making any modifications. While "Can view data source" and "Can edit data source" relate to the underlying data, they do not grant access to modify the report itself. Editing the data source is a separate permission that allows changes to how the data is connected and configured, not how it's presented in the report.
