Hiding page from TOC but still including it in structure.

[RR-N]

Suppose I have the following TOC:

format: jb-book
root: intro
chapters:
- file: mini-unit-1.ipynb
- file: mini-unit-2-intro.ipynb
- file: mini-unit-2-full.ipynb
- file: mini-unit-3.ipynb

How can I hide mini-unit-2-full.ipynb from the TOC, yet still have the "Next" button on the mini-unit-2-intro.ipynb page and the "Back" button on the mini-unit-3.ipynb page?
