3D Security for Custom Payment Gateway

We developed a custom made VISA/MasterCard Payment Gateway on IMIS Version 20.2.66.1216. Recently VISA/Mastercard upgraded their security and we should quickly adopt 3D Security Version 2 that requires users to be authenticated by their bank.

How can we implement this new requirement as there is no provision for a custom made payment gateway to open a challenger modal form on the user interface. do we have an SDK that supports this?
