What is a way that you can mark a knowledge article for review?

The 'Flag article' feature in ServiceNow Knowledge Management allows users to submit feedback about a published article, such as reporting errors or suggesting improvements, thereby marking it for review by content managers.

'Review' is a general action, not a specific system feature for users to mark an article for administrative review.

Bookmarking an article is for personal reference and does not initiate a review process or notify content managers of issues.

'On Hold' is a status typically associated with tasks or incidents and is not a feature for marking a knowledge article for review by users.
