\tcolorbox 损坏问题

Question

我想打破这个tcolorbox：

\dominitoc

\begin{tcolorbox}[breakable,
    enhanced,
    title=\Huge{Contents},
    colframe=orange,
    colback=Silver!75,
    colbacktitle=Gold1,
    fonttitle=\bfseries,
    coltitle=red,
    attach boxed title to top center={yshift=-0.25mm-\tcboxedtitleheight/2,yshifttext=2mm-\tcboxedtitleheight/2},
    boxed title style={
        boxrule=0.5mm, 
        frame code={ \path[tcb fill frame]([xshift=-4mm]frame.west) -- (frame.north west) -- (frame.north east) -- ([xshift=4mm]frame.east) -- (frame.south east) -- (frame.south west) -- cycle; },
        interior code={ \path[tcb fill interior] ([xshift=-2mm]interior.west) -- (interior.north west) -- (interior.north east) -- ([xshift=2mm]interior.east) -- (interior.south east) -- (interior.south west) -- cycle;} 
    }
]
    \csname @starttoc\endcsname{toc}
\end{tcolorbox}

如您所见，我使用了tcolorbox包含 的\csname @starttoc\endcsname{toc}。如果我想以这种方式拆分它：在第 1 部分（第一部分）处拆分，在第 2 部分（中间部分）处拆分，在第 3 部分（最后一部分）处拆分。请记住，我的documentcalss{book}分为 3 个部分，每个部分包含 3 个章节，每个章节包含多个部分、小节和小节。

我该怎么办？非常感谢，并致以最诚挚的问候

尝试

\addtocontents{toc}{\protect\tcbbreak}
\part{title} % for 2nd and 3rd parts
