OAuth2SAMLBearer Destination

The concept name was not provided, and the supplied sources do not contain enough shared, clearly defined subject matter to produce a grounded, accurate definition. The sources reference topics such as principal propagation between SAP BTP environments and OAuth flows, but without a specific concept name it is not possible to determine which of these — if any — is the intended subject. Please provide the concept name so a precise, source-grounded definition can be written.
