Answer 1

Hello Otmane Oulbaz ,
you can make a Copilot Studio agent automatically answer in the user’s language, but doing it correctly requires more than just adding a “language instruction” prompt as a tool.

Right now, Copilot Studio does NOT automatically detect the user’s language in Teams, and tools cannot override the agent’s root system prompt, so the agent falls back to English unless you implement language control correctly.

Add a Prompt.
inputs for prompt:

response:System.Response.FormattedText

query: System.Activity.Text

Now, ask the prompt to find the language of the query and translate the response to the language of the query.

now send the out of this Prompt as a message.
