I am trying to install the keycloak-nodejs-connect middleware into my app. It isn't working well, so of course I'm thinking of trying a different openid-connect client library. What does the keycloak-nodejs-connect library do that other openid-connect client libraries doesn't do? It looks like one unique thing is that it listens for a logout request to be sent from the keycloak admin console, but I'm not sure as docs don't exist.
