Which ExchangeServerApp is the right one? How to tell?

From running HCW multiple times w/ various exceptions, we have a number of separate ExchangeServerApp instances in Entra.

How can I definitively tell which one (or more) is the correct instance? I can't find any of the UUIDs in the Entra entries anywhere in the Exchange Server configuration.

I can't run the ConfigureHybridExchangeApplication script because (from the error it gives) it doesn't handle the multiple app identifiers.

I submitted feedback but haven't heard back from the CSS-Exchange people.

Any guidance appreciated.
