It seems, there is no published documentation or whitepaper or anything for Oracle Identity Cloud Service & EBS integration, yet.
However, you should take a look at the tutorials:
https://docs.oracle.com/en/cloud/paas/identity-cloud/tutorials.htmlMaybe, you can be implement :
Oracle Identity Cloud Service: Integrating with Oracle Access Manager (OAM)
But, as this document is not specifically written for EBS, it will be a big adventure for you..
