OAuth 2.0 is not supported for External API(custom CDS view), but it is visible(ticked) in "Supported Inbound Authentication Methods" of created communication arrangement.

SAP S/4HANA Cloud Public Edition

Currently, the Custom Communication Scenario sets all supported authentication methods to available due to the possibility that different services can support different authentication methods. It is not dynamically calculated what methods are supported in the end.

External API(custom CDS views) at the moment don't support OAuth 2.0.
