How to set up Angular Language Service in Neovim

My setup at the moment looks like this:

local cwd = vim.fn.getcwd()
local project_library_path = cwd .. "/node_modules"

local cmd = {
DATA_PATH .. "/lsp_servers/angularls/node_modules/@angular/language-server/bin/ngserver",
"--ngProbeLocations",
project_library_path,
"--tsProbeLocations",
project_library_path ,
"--stdio",
}

require'lspconfig'.angularls.setup{
cmd = cmd,
on_new_config = function(new_config, new_root_dir)
new_config.cmd = cmd
end
}



On :LspInfo, I can see that the cmd is executable, but somehow it doesn't attach.

I have difficulty to differentiate @angular/language-server from @angular/language-service...

I am not sure what the tsProbeLocations and ngProbeLocations do and if my path is correct.

Finally, I red from Angular Language Service website and there isn't a good guideline for neovim. (except for coc-angular, but I don't use coc.)
