Custom MFA page w/o using widget


We want to enable MFA as part of our login flow. We are already using a custom login page using Auth0.js and want to use a custom MFA page as well.
We were not able to find any instructions/examples on how to create a custom MFA page w/o using the Auth0 MFA widget.
Auth0.js also doesn’t seem to have any functionality related to MFA.

Any help/examples/resources would be appreciated.
