I am creating a custom event object form Application Composer in ERP Fusion environment. After the action: Generate Integration Events from Application Composer, I can see the custom event is published in the custom catalog. But I am not able to see the custom event in the OIC ERP Cloud Endpoint for subscribing to the event. After a day of creating the custom events it does appear in the "Receive Business Events raised for ERP Cloud" option. Is there any process or step which needs to be executed for getting the event available in Oracle ERP Cloud Endpoint immediately after
