After clicking the Save button your client application entry will be created. You now have to go back to the Wildfly instance that the application is deployed on and configure it so that this app is secured by Keycloak. You can obtain a template for the configuration you need by going to the Installation tab in the client entry in the Keycloak Admin Console.

Select Keycloak OIDC JBoss Subsystem XML. An XML template is generated that you’ll need to cut and paste.
