Reviewing and Approving a Translated Article
Translated articles are pushed back when the project status updates to "Project Completed". Articles are either published automatically or pushed in as drafts, depending on the settings you chose during the project creation. You can find the drafts for each language in the Knowledge > Draft Articles section of Salesforce.
Note: If you try to create a project with articles that already have draft translations, a confirmation dialogue opens to confirm if you want to continue with this process. If you continue, translated drafts may fail to push back automatically because of the duplicates.
