Contributors can be given limited access to Canto's Settings page. They're able to manage portals, manage upload links, and add or disconnect connections to Box, Dropbox, and Google Drive.
To enable these privileges, navigate to the Settings and select the User & Groups tag, followed by the Privileges sub-tab.
From here, scroll down to the Consumer Privileges section at the bottom of the screen.
Select which privileges you would like Contributors users to have. They will be able to access the Settings from their profile menu. Only the selected privileges will be accessible to them.
