We are trying to enable an additional language for the bot. Our default language is english. On language enable part we are trying to add german language. Below are the steps which we did.
We do not have any tool in place to do it. It is up to the users to translate or get this translated and import in the bot. JSON schema/ structure should be valid.
Many a times it is observed that Google or other translation service are not very accurate. So, manual translation by language experts ensures better quality.
