Documentation on used highlight groups

[pinpox]

Hello,

asking here because I can't find further docs, hope that is okay. What highlight groups does this parser use? When enabling it, in lines like these:

    home-manager.inputs.nixpkgs.follows = "nixpkgs";

Everything up to the = sign is colored in the same color. When disabling the tree-sitter highlighting, the last argument is colored differently. I'm using a self-written color scheme, not sure what values change which parts of the highlighting.

Where can I see what groups used?
