Genesys Cloud enables administrators to add custom icons to knowledge portal categories through the Messenger configuration interface. To implement this feature, users must first ensure categories are displayed on the knowledge portal and possess the necessary administrative permissions. Icons are configured by navigating to Menu > Digital and Telephony > Message > Messenger Configurations, selecting the desired knowledge portal, and locating the Subject categories section under Components. Each category displays an image placeholder where administrators can add images by clicking the Add image button. The system supports multiple upload methods including drag-and-drop functionality, direct file upload from a computer, or URL-based image insertion. Supported file formats include .jpg, .jpeg, .png, and .gif files, with a maximum file size limit of 25MB. After selecting or uploading an image for each category, administrators must click Save to apply the changes. This functionality enhances the visual organization and user experience of the knowledge portal by allowing customized category identification through icons.
