How do I override the cabalFormattingProvider?

[feature-not-a-bug]

I tried the following which produces an error

vim.g.haskell_tools = {
    hls = {
        haskell = {
            cabalFormattingProvider = 'cabal-fmt' 
        }
    }
}

unrecognized configs in vim.g.haskell_tools: { "hls.haskell" }

Hey 👋
You're missing the settings key.

That did it, thanks!
