How to use dictionary with ltex-cli?

[dpo]

Could you please help me understand how to use a dictionary defined in a JSON settings file with ltex-cli? Here is what I have:

❯ cat ltex.json
{
  "ltex.language": "en-US",
  "ltex.dictionary": {
    "en-US": [
      "GERAD",
    ]
  }
}

❯  echo "I am at GERAD" | ltex-cli --client-configuration=$PWD/ltex.json -

I am at GERAD
        Use 'GERALD'
        Use 'GERARD'
        Use 'GRAD'
        Use 'GÉRARD'

So it seems like the dictionary entry is simply ignored. What am I doing wrong?

Not sure if I should have opened this issue over at https://github.com/valentjn/lsp-cli.

Does the dictionary option work for anybody?
