# tcolorbox: Undefined control sequence \tcbsetmanagedlayer

I don't know why, but I'm trying to change the \tcbsetmanagedlayer defined in tcolorbox in order to increase the number of maximal nested boxes. However, this fail with the error

Undefined control sequence \tcbsetmanagedlayer

I pay attention to put it in the preamble, as stated by the documentation, so I don't understand what I missed. Any idea?

Thank you!

MWE

\documentclass{article}
\usepackage[most]{tcolorbox}
\tcbsetmanagedlayer{5}

\begin{document}%
Hello
\end{document}

\tcbsetmanagerlayer is a documentation typo tcolorbox.pdf.

The macro is called \tcbsetmanagedlayers, not \tcbsetmanagedlayer, note the s indicating a plural here.

Looking into the source file of tcolorbox.sty reveals this.

\documentclass{article}
\usepackage[all]{tcolorbox}

\tcbsetmanagedlayers{5}

\begin{document}%
Hello
\end{document}


I have reported this issue here: https://github.com/T-F-S/tcolorbox/issues/32
