SSO between Oracle Fusion and External website that host the Oracle Digital Assistant (chatbot)

Hello Gurus - 

    Hope you are all doing fine today. We have this requirement where there would be a link inside  Oracle Cloud Fusion application that once clicked will redirect to an external website that hosts the ODA chatbot. The chatbot that is embedded in this external website should be able to identify the current user that is currently logged-in  from the Oracle Fusion Application. 

I think this is SSO functionality but not really clear to me yet how can this be implemented.

Thank you in advance!
