Neovim + LanguageServer.jl

Tooling
2

I was trying to use your solution in neovim, but unfortunately it does not work for me.

LspInstallInfo gives:

{                                                                                                                                
  julials = {
    is_installed = true
  }
}

with a .jl file open and invoking

lua print(vim.inspect(vim.lsp.buf_get_clients()))

gives

{}

So, certainly there is something wrong.
My init.vim looks like this:

call plug#begin('~/.local/share/nvim/plugged')

Do you see any immediate problem here?
