Hi, im 20 minutes old to Super Token. Important question for me is - how do I implement consent (u know - opt to agree to being contacted stuff). I started on Auth0, seems need to pay $$$ for consent management plugins to get this startup basic job done. Pointers please?

We don’t require you to use OAuth protocol. Therefore, we don’t have scopes and no consent screen. Just regular sign in and session management.
