Neovim support?

I'm trying to use this in Neovim from Lazyvim. I added this to one of the plugin file. It installed fine and I can see it running but I don't see the syntax highlight while looking at "config.kdl" for Zellig.

`return {
{ "imsnif/kdl" }
}`

Reproduce the report in Neovim with LazyVim using the shown plugin configuration and a config.kdl file. Identify why syntax highlighting is not activated, then verify that KDL highlighting works in Neovim; the issue provides no file or test entry point.
