Issue in ./help/using/integration/integration-aep/aam-aep-audience-sharing.md

Customers find it hard what is the minimum set of IDs needed for segments sharing to work between AAM to AEP. For example, is ECID always needed? Will this work if customer has a Declared ID (like CRM ID) but no ecid in AEP?
