Hey, thanks for the PR!

Before I can merge this, could you please do the following please?

• Make the PR against botpress/botpress repo, branch develop/x (this repo is moving to the botpress repo this week)

• Remove Bale from the PR and open a separate PR for it (we don't merge new non-official modules in the official repo), but we do accept PRs and we might merge it if many people need it

• Run Prettier on the code to respect code styling

Thanks!
