When trying to run eldoc-box-help-at-point there is the following error.

Debugger entered--Lisp error: (void-variable eldoc-doc-buffer-separator)
  eldoc-box--help-at-point-async-update((("```typescript\nconst error: string\n```" :buffer t)) nil)

It might been a byte compile issue.So on trying to recompile. It gave the below warning.

Thanks for the great package and contributing to emacs ecosystem

Thanks! It seems that eldoc-doc-buffer-separator is only added in Emacs 30. I added a blank definition for it in eldoc-box.el. That should fix the compiling error.
