Hey @reshmee011 , any chance you might be able to test out this auth mode ? Just saw you do some interesting stuff in this area and was wondering if you might be able to help here with the FIC approach, no pressure 😊
Appreciate any help in this.

@gautamdsheth : that's a very cool addition/feature. I will try to spare some time over the weekend to test it. Thanks so much to make the product better.
