Assessments synchronization with Oracle Integration Cloud

I have some questions related to our customer implementation:

1. I am looking for the ability to sync the assessments from OIC to Oracle recruitment. Like any API or Webhook.

2. I am unable to find out the place where we can do the configuration like, setting an assessment to be sent to a candidate when he/she applies to a job.

3. Once a candidate completes an assessment (Sent via Recruiting), do we need to make an API call from our customer system over OIC, to update the candidate status on Oracle?

4. Can you provide me with the complete cycle of this integration, with all the details, like screens, a user with required permissions, a demo account with some dummy jobs and candidates for testing purposes. etc.
