[keycloak-user] how to register keycloak event Listener provider SysoutEventListenerProvider

Hi , I just wanted to read events generate by keycloak in my spring boot application . e.g. Any new user recently added /removed or deleted from keycloak should emit an event and fire an my Spring Boot application API so that I can update the user information in to my application. I just wanted to know how do I register e.g. SysoutEventListenerProvider in keycloak ? as I do not see a UI provision in I came across the git code @ https://github.com/keycloak/keycloak-quickstarts/blob/latest/event-listen... But not really sure where do I put below SysoutEventListenerProvider class in keycloak so that onEvent would automatically gets triggered where I can write my custom logic to hit my Spring Boot API for further action
