Expert language server doesn't find project symbols in Zed

Hi all, I am trying out the new Expert LS in Zed. None of the symbols functionality is working: Cmd-T, go to definition, reference, etc. Am I missing something?

settings.json:

    "Elixir": {
      "language_servers": [
        "expert",
        "!elixir-ls",
        "!next-ls",
        "!lexical",
        "..."
      ]
    }
```

Maybe….

Have the same issue in other editors. Expert is still young (but project renaming from Newbie to Mediocre to Expert would be a mess)
