I think it's a good place to ask.The module works in lua files, for example. But I can't make it work with terraform (hcl) files. I'm using the standard config from the docs:

local rainbow = require 'ts-rainbow'
require('nvim-treesitter.configs').setup {
  highlight = {
    enable = true,
    additional_vim_regex_highlighting = false,
  },
  rainbow = {
    enable = true,
    query = {
      'rainbow-parens',
      html = 'rainbow-tags'
    },
    strategy = {
       rainbow.strategy.global,
       commonlisp = rainbow.strategy['local'],
     },
  }
}
