Hi @MicSG-dev. There is an existing high level issue about this here: #28
I believe the final step is tracked here: #712

You'll be glad to learn that, thanks to the amazing work from the Arduino community, we have already reached 100% translation coverage to Portuguese as well as several other languages:
