Neovim - Elixir Setup Configuration from Scratch Guide

Embarrassingly I had too many tabs open and realised I replied to the wrong thread…it won’t let me repost the same and I can’t delete the old one, but can see here: Neovim: nvim-lsp + elixir - #17 by te_chris

Basically, I’m using nvim and the NVChad config. Have installed the elixirls package with mason and LspInfo says it’s being used. I’m not getting any completions though. Debug suggestions welcome!
