You do have to flip a switch in Parameters panel:

Configure this as an agent to avoid having to set it each time.

Thanks :),

I have the same issue now but with web search. Is it something i have to do server-side?

[danny-avila]

Azure specifically doesn't support Web Search yet, please read: https://learn.microsoft.com/en-us/azure/ai-foundry/openai/how-to/responses
