Help with namirial OTP: script?

[alfredonodo]

Hi,
I recently found out that namirial is about to remove the option to use SPID with SMS. You can choose to pay for the subscription that includes the SMS option or install their OTP app.
So, after some research on the web, I found this script. I tried to see if I can reuse it with namirial, but I think it's not possible since I couldn't find any way to get useful information during the registration process.
Do you know of a similar script for namirial? Do you have any suggestions on what I can do?
Thank you
