I want users to be able to search our data warehouse using looker but I do not want them to be able to download any data. Is there a way to disable the download feature for certain users?
Have a look at the permissions download_with_limit and without the limit: https://cloud.google.com/looker/docs/downloading
If you want the permission to be disabled by default, you may need to uncheck the permission for the default Permissions sets (User, Creator)
