How to configure step-up authentication when using an external IDP as 2nd Factor ?

Solution Verified - Updated -

Issue

Step-up authentication is working fine when using as a 2nd condition OTP. In this case the access token has the ACR value set to level 2.

But when the 2nd condition is external IDP, the ACR value level remains at level 1, although it should have been set to level 2.
