When creating a workflow, you can add multiple languages to it. To add additional languages, follow instructions below:

1. Create a new workflow or select from a list of already existing workflows

2. Select a default language

3. Once the workflow opens, select additional languages

4. Select either to "Auto-translate" or "Copy content from default". By selecting auto-translate, you will be able to do changes in the translation. If you choose to copy content from default, all input will have to be added manually. 

Please note that changes made in a default language after another language is added might not be translated into the other language. Therefore, it is best to add a new language once the workflow in a default language is completed.
