Assistants are designed to work in a single language. However, you can create multiple assistants in various languages and incorporate them into your resource center.
Start by creating a separate assistant for each language. You can select the language in the assistant builder. Ensure each assistant is trained and published.
Then, in your resource center, add an AI Assistant block for each language. Choose the appropriate assistant for each block. Enable Only show block if and include an Attribute condition. Select the Locale Code attribute and set it to match the correct locale code.
