[keycloak-user] Can some one point me in the right direction

First thanks for all the help I have had so far. I currently have a client using direct access to get a grant from KeyCloak via the protocol/openid-connect/token url. The two direct access requests I need that I am having problems tracking down are; 1) Getting a new grant using the refresh_token 2) Getting a grant for a bearer only client using (I assume the access token).
