Tufte-Book does not work with tcolorbox

[JacobBeckey]

I would like to be able to write multiple page proofs, contained within tcolorboxes, while still including sidenotes in the tufte style. Is this a feature that can be added? Or, does someone know a work-around?

As a possible solution add this to your preamble:

\makeatletter
\let\l@tcolorbox\l@figure
\makeatother

The reason for this can be found in: https://tex.stackexchange.com/questions/554232/list-of-tcolorbox-in-tufte-book

This sadly did not work. I would like to include both figures and sidenotes in the margin of a page with content contained within a tcolorbox. Any other ideas?
