[LanguageServer] How to provide initializationOptions for uses completion( nvim )

[Crashdummyy]

I am currently not able to get the languageServer fully functional.

While all the basic stuff works I cant find out how to use the advanced functionality.
https://github.com/actions/languageservices/tree/main/languageserver#providing-advanced-functionality

I am setting this up following the specification. -> https://neovim.io/doc/user/lsp.html#lsp-quickstart

{
    cmd = { 'gh-actions-language-server', '--stdio' },
    filetypes = { 'yaml', 'yml' },

    root_dir = function(filename)
      return filename:find('/%.github/workflows/.+%.ya?ml') and require 'lspconfig.util'.root_pattern('.github')(filename) or nil
    end,
    single_file_support = false,

   initializationOptions = {
          sessionToken = vim.env.GITHUB_TOKEN,
          logLevel = 1
    },

    capabilities = {
      workspace = {
        didChangeWorkspaceFolders = {
          dynamicRegistration = true,
        },
      },
    },
  }

But while it does work using the visual studio code after the login I cant figure out how to get the completion working here.

When I provide some bogus for the session token it fails to fetch action/upload-artifact all together so the token is definitely passed.

Completion also does not work for me in VS Code.

Hover on those same with arguments works both in VS Code and Neovim.

Its very weird...
WHen I installed the plugin in vscode I had to sign in and I additionally had to restart vscode for the completion to work.
But it does work now ( I dont want to use vscode tho )

It looks like only the completion doesn't work 😆 when I try to add some bogus or miss parameters I get some errors in nvim
