Aeap first time trying..change language

Hi everyone… I’m struggling for the first time with aeap with the google speech api…
followed the link GitHub - asterisk/aeap-speech-to-text: Asterisk external speech to text application and everything seems to work fine. for English.
One thing I can’t seem to get and even testing by modifying languages.js and/or aeap.conf with the @language=it-IT directive
it always tells me
ERROR[3799]: res_aeap/aeap.c:204 raise_msg_handler: AEAP (0x7f3c2c004f40): Language ‘it-IT’ not supported

can some good samaritan show me how to do it?
I have read previous posts about it but I didn’t succeed
Sorry

ok…for Italian you need to modify languages.js and provider.js
the first
const supported = [
“en-US”,
“it-IT”,
];

the second
static languages ​​= [
“en-US”,
“it-IT”,
];
And
const DEFAULT_LANGUAGE = “it-IT”;
