List of tcolorbox in tufte-book

Question

Normally tcblistof works fine, but not with the tufte-book class and I cannot figure out why. Here is a MWE.
documentclass{tufte-book} 
% documentclass{book} % this works
usepackage[theorems]{tcolorbox}
newtcbtheorem[auto counter,number within=chapter,list inside=thm]{theo}{Theorem}{}{}

begin{document}
    tcblistof[chapter*]{thm}{List of Theorems}
    chapter{Chapter No1}
    begin{theo}{Theorem No1}{}
        lipsum
    end{theo}
end{document}

Using the book class works as expected. What do I have to change for tufte-book?

OP has already found a solution in this answer. Here I'd like to provide some general discussions.
tufte-book class contains lines
% Only show the chapter titles in the table of contents
setcounter{tocdepth}{0}

and since tcolorbox defines l@tcolorbox as level 1 by
newcommand*l@tcolorbox{@dottedtocline{1}{1.5em}{2.3em}}

therefore tcblistof[chapter*]{thm}{List of Theorems} produces nothing but a list title.
Locally using setcounter{tocdepth}{1} is a workaround, but the produced list entries may not share the same style with list of figures and tables. Currently entries in these two list are defined as
newcommand{@tufte@lof@line}[2]{%
  % #1 is the figure/table number and its caption text
  % #2 is the page number on which the figure/table appears
  leftskip 0.0em
  rightskip 0em
  parfillskip 0em plus 1fil
  parindent 0.0em
  @afterindenttrue
  interlinepenalty@M
  leavevmode
  @tempdima 2.0em
  advanceleftskip@tempdima
  nullnobreakhskip -leftskip
  {#1}nobreakqquadnobreak#2%
  par%
}

renewcommand*l@figure{@tufte@lof@line}
letl@tablel@figure

Hence OP's answer letl@tcolorboxl@figure is a good idea.
