I can't understand about is what happens when I publish the bot beyond the test canvas, for example on a demo website. I don't see any language selection option or any multi-lingual toggle there. am I missing something?

Here's the documentation on how to build a multilingual bot in Copilot studio. From the article the basic process is to create the workload of the bot for each language as a "Skill". Then in the welcome to the bot you can ask which language the user wants and call the appropriate "Skill". There is no direct support for multiple languages in a Copilot bot. Each bot or Skill must be in a specific language. Set up a multilingual bot to use in voice channel | Microsoft Learn
