Criteria-based record page components are components that only display on a record page when certain conditions are met. For example, you can show a component only when the case status is closed, or when the case priority is high. This way, you can reduce the clutter on the Lightning Service Console and make it easier for service representatives to find the tabs and features they need. You can use the Lightning App Builder to define criteria-based record page components for different objects and apps. Verified Reference: [Criteria-Based Record Page Components]
