Is there a way to use the `daml codegen js ` command to generate an ESM build? I am having issues using the generated libraries with the Vite build tool because it is a commons library.

At the moment, you’re stuck with commonjs. I’ve opened a feature request [ESM support in JS Codegen · Issue #13615 · digital-asset/daml · GitHub](https://github.com/digital-asset/daml/issues/13615)
