Amazon Lex Slot type AMAZON.Number

Hey guys

I'm using Amazon Lex in pt_BR with Slot type AMAZON.Number

The documentation states that this slot Converts words or numbers that express a number into digits, including decimal numbers.

I'm creating a voice bot where I need to ask for a numeric password.

The problem that is occurring is that there is no conversion to digits in the pt_BR language

I need to convert to digits to pass to a lambda function
