Genesys Cloud enables users to update CX Cloud packages from Genesys and Salesforce through the Lightning component tab "CX Cloud Genesys Settings" in Salesforce. Users can access this tab by clicking the App Launcher on the Setup Home page, searching for "CX Cloud Genesys Settings," and selecting the corresponding Lightning app to view all available packages for installation and upgrade. The update process involves clicking the "Update" button for the desired package, allowing organizations to maintain current integrations with the latest features and capabilities. This functionality requires prior installation of the CX Cloud from Genesys and Salesforce package and provides a streamlined method for keeping CX Cloud integrations up-to-date with new functionality.
