[keycloak-user] [development] Jumping to another flow from an authenticator

Hi, I'm doing experiments with authenticators... I've made an authenticator for the "first broker login" flow and I'm wondering if, under certain condition I implemented inside the authenticateImpl method of the authenticator, I can jump to the browser flow to "challenge" the user with the regular login screen. It looks like it's impossible by design. If there's another alternative, you can think about, it would be great. Thanks.
