Highlight Definitions not working at all

When enabling highlight_definitions and trying to hover with cursor over a symbol, no other symbols are highlighted.

To Reproduce 1) Enable nvim-treesitter-refactor highlight_definitions as provided on the documentation 2) Try to create a simple program (C in my case) which contains a symbol definition and usage 3) Try to hover with cursor over the symbol usage 4) The original definition is not highlighted

Expected behavior The original definition of such symbol should be highlighted

Run :checkhealth for more info

Additional context Running :checkhealth against nvim only returns that I do not have pynvim installed. Unsure whether that could be the issue.
