In the "lead Gen with AI" template we have this conditional on the AI Dialogue variable being greater than 5. But greater than 5 "what"?

Initially I thought it would be greater than 5 questions in a row asked by the AI, but on the third question the flow has already ended. I want to understand the logic in this template please

Does anyone have a full tutorial on how to use these two options? Inside each one there are several fields to fill in and I don't understand what to do.

Unfortunately the docs don't have much explanation https://docs.typebot.io/editor/blocks/integrations/openai#tools

For example, in this image taken from the link above, why are you using the append variable? don't get the logic
