Certain add-ons may require an additional system-, organisation-, group-, or user-specific add-on configuration in order to function. For example, this could be a preferred user, group or default setting of the add-on or an authentication token to connect with a third-party system. This is highlighted once the add-on has been installed.
Once an add-on is installed, navigate to the installed page under the Marketplace tab; within the add-on's details page, click the Configure link.
Users can configure the add-on in the pop-up dialogue. Once the add-on has been configured, it will be highlighted accordingly.
Note: this label does not specify whether the add-on has been correctly configured, it only indicates that configuration options have been adjusted from their default setting.
