Question: ClientCredential RFC8693 Token Exchange Support

[weihong-xu-hpe]

There is cases in our client credentials 2 leg oauth2 flow we need to do a token exchange. I have see in discussionthat for 3-leg auth url process, we have an exchange function which can be used for this Purpose.
However this is not in the clientcredentials package. I check RFC page. It does not limit the exchange behaviour.
