Integrate web browsing into a prompt chain

[fudu69]

I would like to create a chain which takes as entry point the name of a scientific field and look on Internet for last main announcements in this field. Then, the output (text of main announcements) is sent to a LLM with a system prompt that make a nice summarize of it.
It would also be great if I can have the sources included.
(Precision: I don't want to scrap a specific website. I want to browse the web.)

I can't manage to integrate webbrowsing into a chain neither to guide the browsing with a system prompt.
It seems that it's only possible to let an agent use webbrowsing while chatting with the user. No control of the browsing and not possible to take the output of the browsing as input for another LLM call.

I already implemented this kind of behaviour in LangChain.js directly. It's also quite simple to do it with n8o. But I'm just beginning with Flowise UI. What am I missing?
Thank you!
