AWS SNS Push notification for MFA/Step-up

Help
1

I’m exploring different options for MFA provided by Auth0. I have a question regarding Push notification for MFA/Step-up authentication. Is there a way to have Push notification for MFA/Step-up authentication to Amazon SNS ? I see Auth0 do have integration to AWS SNS, but the documentation is not clear if this is enabled only with Guardian app or can It work by its own. i.e., our internal service consumes the push notification from AWS SNS sent by Auth0 and display it on client’s mobile app owned by us. Essentially, I’m trying to have Push notification on AWS SNS without any dependency on Guardian App/SDK
