Embed in a web page

How it is done to embed the chatbot in a webpage (not the floating bubble)?

I have been searching but I cannot find it…

This is what I mean, the chatbot should be in the main body of one website page.

do you want it to cover the entire page and always opened?

No… I meant embedded inside the page, not over covering the whole page.
