Implicit grant scenario for oAuth2?

Is it possible to use an implict grant scenario ( https://tools.ietf.org/html/rfc6749 ) for oAuth2 in SAP?

I use the Authorization Code Grant scenario now, and this seems to work nice. For use in UI5 applications the Implicit Grant scenario seems more appropriate. (in the authorization grant scenario the client secret will be visible for end users in the javascript sources..)

I would expect that instead of the '/sap/bc/sec/oauth2/authorize?response_type=code' call, i need to do a call like '/sap/bc/sec/oauth2/authorize?response_type=token' . I started the debugger, but it seems that this scenario is not implemented in the SAP code?

Thanks,

Joris
