Voice assistant: some languages do not work

I am testing voice assistant in my native language Hindi. But it seems that the intents are not configured. Is there a way I can modify the intents in my local HA install to test? I am checking the intents here:

intents/sentences/hi at main · home-assistant/intents · GitHub

The intent for light_HassTurnOn.yaml is:

language: hi
intents:
  HassTurnOn:
    data:
      - sentences: []
        slots:
          domain: light
          name: all

I can add sentences to test if they work or not. Is it possible?

Same problem, Norwegian Bokmål is missing in HA. Is it possible to configure locally?
