[keycloak-user] How to use jaxrs-oauth-client for authorization code grant?

Hi, I'm looking for a way to use the authorization code grant flow using a pure jaxrs filter. So far, I've successfully added the jaxrs-oauth-client ( https://github.com/keycloak/keycloak/blob/master/adapters/ oidc/jaxrs-oauth-client) to my rest app, which sends errors on requests without a token. Then, I wonder if jaxrs-oauth-client supports the authorization code grant? This class https://github.com/keycloak/keycloak/blob/master/adapters/ oidc/jaxrs-oauth-client/src/main/java/org/keycloak/jaxrs/ JaxrsOAuthClient.java has some methods about redirect but I couldn't find any example. I want some URLs to send redirects to auth server instead of auth errors, like in the vanilla getting started guide and without using wildfly/jetty/tomcat/spring adapters. Thanks
