Install Client Bundles - There is a Scan for Client Bundles button that allows you to scan for new or updated client bundles and install them.
Delete Client Bundles - A list of all installed client bundles is displayed with a checkbox next to each bundle. From the list, select the bundles that you want to delete and then click the Delete selected bundles button below the list to delete the selected client bundles.
