The Minimum Viewing Role feature provides functionality to control when a Comparison Set gets displayed on a page.
To access this feature head over to WordPress Admin Area -> Datafeedr API -> Comparison Sets.

By default, this setting is set to "none."
This means that Comparison Sets are always visible on the pages where they're posted, with no viewing permissions required.
For additional options, click on the setting to view the full permissions available. This includes various roles such as administrator, editor, customer, etc.

Simply choose the required role to view Comparison Sets before they’re displayed by selecting your preferred permission level from the options.
