Open Data Domains
Assets on open domain types have two permission levels, public and private. Public assets are accessible to all visitors of your domain and can be discovered through the site-wide data catalog(if not hidden from the catalog by site admins).
Private assets can only be accessed by the dataset owner, users on the site with the appropriate permissions, or users with whom they've created a share with using the Sharing tool. You can read more about permissions here.
Changing the permissions of the dataset will now be done through the action bar. To do so you will need to select the "kebab" icon on the bar and then Manage Viewers.
From there you can select the audience of the dataset as Private or Public. The current state of the dataset will be highlighted.
Note: It may take up to 15 minutes for your dataset to be re-indexed and for the site-wide data catalog to be updated. The actual permissions change, however, occurs immediately.
