ACUL - Writing to user-metadata on ACUL screen

I’m trying to implement a POC for a new feature using ACUL. I added a new checkbox to the mfa-sms-challenge screen and I need to make this user selection available in an Action Script that runs as part of the post-login flow.

Things I’ve tried:

  • Writing cookies from ACUL. The Action script doesn’t seem to have any way of reading them.
  • Pass this information as a custom option as part of the SDK’s mfaSmsChallenge.continueMfaSmsChallenge(options). I see the option gets sent to Auth0 in the dev tools, but I’ve found no way to access it in my actions.

I’m currently trying to write this to the user’s metadata, but I don’t see any option in the ACUL SDK to do so.

Is this possible to do? If not, do I have any other options?
