[keycloak-user] understanding the photoz example

I have been going through the photoz example and I am curious how does the drool application know the resource owner [1] or get details about the resource in general ? Can this be done with a javascript based policy? Is there a post/description about how the photoz example works and how information flows in this example. I am trying to understand via the code as of now, the Readme is a good introduction of what it does, but not enough to understand what's really happening? I am having a hard time understanding how to setup keycloak authorization and also missing documentation/explanation on how to do things. If there's a resource that someone could refer to, that would be great. [1] https://github.com/keycloak/keycloak/blob/master/examples/authz/photoz/ph... Regards, Avinash
