Automatically fill in SMS passcodes doesn't work

Hi,

According to the following link when i get temporary SMS passcode, i should see it on my keyboard and be able to touch in order to enter the code instead of typing the number manually:

For some reason this feature doesn't work for me on iPhone11 with iOS 13.2 - don't see any code suggestion after getting the SMS.

Is there any settings definition i should define in order to start using it?

Thanks a lot.
