[keycloak-user] Alternative authentication flows

Dear experts, we are working with Keycloak 4.0.0. We want to implement the following authentication workflow: 1) Mandatory User/Password 2) If User/Password corrected then mandatory one between 2.1) Google Authenticator 2.2) Another factor of authentication We are only able to make the first challenge mandatory, while we are not able to choose the second mandatory option. If we set them as Required will be chosen both in sequence ("Google Authenticator" AND "Other factor"), while we cannot choose "Google Authenticator" OR "Other factor". Could you please advise? Thanks
