[keycloak-user] Changing url in reset-password emails

Hi, We use keycloak API rest to send email password reset to users. But we would need to change the host part of the url used in the email link presented to users in the email sent to them. Is there an easy way to do so, you guys know?? This is quite critical right now for our app so any help would be MUCH appreciated. THANKS A LOT Fabio Monteiro
