onenote API using python: adding more text to a page

I'm trying to add some new text to a page knowing the page id referencing this https://docs.microsoft.com/en-us/graph/onenote-update-page

I just want to add a new text box. It seems like it is just another div to the html. How do you just add a div into the body?

I want to insert a new text box that says "hello world".

I've tried the code on that page and all it does is add to existing text boxes.

I'm using python requests.
