Description

Review if we have some automated tests for the scenario outlined in the authorization chaining across domains documentation: #45466 .

It is possible that we have automated tests for this already. But maybe not (maybe we have tests for testing issuing access-tokens for specific audience and in different place tests for rfc-7523 authz grant). We can maybe add some simple automated test class for testing both parts (domain-a, domain-b) to make sure that we test the use-case, which we document.
