For Google Home, I have a pin Intent which takes 4 digit pin for a banking application.
I defined its entity type to "number sequence" but that doesn't seem to work for specific sequences. Interestingly whenever there is 2 & 1 inbetween (for eg 2212,3212, 4212.. etc) it interprets it as 2 to 1/2, 3 to 1/2 and so on.
What is the best way to define pin so as to get 2212 when I say 2212
