Switch to use Oauth 2.0 credentials based authentication from Basic Authentication to secure

[#1]

Hi,

We are planning to Switch to use Oauth 2.0 credentials based authentication from Basic Authentication in IS to S/4 Private cloud connectivity as shown in attached blog. https://community.sap.com/t5/technology-blog-posts-by-sap/sap-integration-suite-connecting-to-s-4han...

But the option for Odata receiver adapter only shows Basic Or Principal Propogation https://me.sap.com/notes/3457515/E

Need clarity from SAP when this functionality is possible and how to switch from Basic authentication to Oauth 2.0 based authentication or if more secure options available to connect IS to S/4 Private cloud ? 

Br,

Sanjay
