How To implement full Oauth2 schema on Caché/HealthShare ?

Hi, 

I am a beginner on intersystems technologies ! and i want implements Oauth2 for our projects ( Angular 2 + Caché REST  Backend). 

i read the article that the link  is below : 

https://community.intersystems.com/post/cach%C3%A9-open-authorization-framework-oauth-20-implementation-part-1

But : i need to create  all servers ( Auth and Resource ) on Caché and dont' to use google server.

Also, i need   to be able to consume Oauth from my web services as caché REST application (whitout csp ui) .

An Idea  Please ?

Thank you
