coc.nvim extension

[anhnamtran]

Hiya, I'll get straight to the point. I use this plugin extensively, the one thing I'm missing is the completion. I see that support for nvim-cmp is already built in, I'm wondering if the helper functions for that could potentially be used/extended for other completion plugins. In my case, I'm wondering if there's a starting point to build a coc.nvim extension for completion.
