Sorry you are having so many issues. That has not been my experience with elixir-ls either locally or in Codespaces. Just want to say that when you do get it working, it does indeed have that and many more features. If you are interested, the Elixir slack is very active and helpful and there is a #language-server channel.
Thank you! It seems the Elixir LSP does provide useful features... I'm worried that even after getting it working on my Mac, the same troubles happen again when I move to remote machines. I'll try the Elixir slack!
