How to enable for specific languages?

[woile]

Hi, I open this discussion to find out how to enable the plugin just for certain language (markdown in my case).

I've been searching with no success. I have this so far, but it doesn't work:

{
  "lsp": {
    "harper-ls": {
      "initialization_options": {
        "enabled": false
      }
    }
  },
  "languages": {
    "Markdown": {
      "enable_language_server": true,
      "language_servers": [
        "harper-ls"
      ]
    }
  }
}

has anyone been able to achieve this?

Thanks!
