[keycloak-user] Email verification before user registration

Hello, Is there a way to verify user email before completing the user registration ? Thanks for the tips ! P.S. I've tried to create custom FormAuthenticator and FormAction to display a first page in Registration Flow, adn send a verification email, but I'd need to resume the registration flow when the user clicks on an email link (and I don't know how).So I suppose, this is not the way to go.
