[keycloak-user] Getting the user id from the access token

Hi I want to be able to update the user password and some preferences from my web app, in order to update some of the user info from my portal i can see in the rest api that you need the user ID. I have a backend with java that should connect to my keycloak server once it gets the token KeycloakSecurityContext securityContext = (KeycloakSecurityContext) httpRequest .getAttribute(KeycloakSecurityContext.class.getName()); AccessToken accessToken = securityContext.getToken(); I dont know how to get info from the accesToken, or does the access token class already has methods to do that. I know this is more of a question of design. This part is not really clear for me. Thanks
