How do I enable the documentation pop-up when coding in an lsp buffer?

I just migrated from spacemacs, and I’m trying to make the coding experience sorta like that.

What happened?

When in an lsp buffer I expect a pop-up with documentation like in spacemacs/vscode. However I can’t get it to work. I’ve tried explicitly enabling lsp-ui-doc-mode, but no luck so far.

What did you expect to happen?

I expect the documentation to, well, pop up XD

Steps to reproduce

  1. Explicitly enable lsp-ui-doc[a]
  2. Go to an Elixir buffer (the language I’m coding in)
  3. Hover over a module/function with documentation


(after! lsp-ui
 (setq lsp-ui-doc-enable t))
