Unfortunately, the term provider is ambiguous in this context, and it becomes pretty apparent here 😅
- In the context of Cloud SDK, provider typically means the BTP subaccount in which this currently running Java application is hosted, i.e. the provider tenant
- In the context of IAS App2App, provider refers to the target system that is providing the API, and the currently running Java application acts as the consumer
I don't see an easy way to resolve this confusion, other than adding an explicit comment here that the difference apptid:provider-tenant-id vs. app_tid=PROVIDER_TENANT_ID is expected and intended.

LGTM, ty for contributing 🥳
Adding a small release note would be good, but we can also do that in a separate PR to accelerate merging this. @newtork would leave that up to you depending on when we want to press the release button 😉
