What exactly is aep.connection.auth.client.code ?

[daniel-torrecillas-dsg]

Does anyone know what aep.connection.auth.client.code actually refers to?

I see the Description for that row in the table on this README says "IMS client code", but I don't see that at https://developer.adobe.com/console for my project. I only see "Access token", "Client ID", "Client Secret", "Technical Account ID", "Technical Account Email", and "Organization ID".

I tried using the access token for aep.connection.auth.client.code, and the Kafka Connect connector returned:
