Set custom chatbot language through code

I wonder if it is possible to set the language to use on the widget integration code or via api.

to understand each other

<script>

window.chtlConfig = { chatbotId: "xxxxxxxxx" }

window.chtlLang = { chatbotLang: "It" }

</script>

If I have a multilingual site, my browser is in English, but I choose the French version, I would like the chatbot to be set in French not in English
