删除tcolorbox中内框的圆角

Question

我有以下 LaTeX 代码，它使用 tcolorbox 创建一个警告消息框，并在外框的西侧放置一个警告图标（三角形警告标志），但在我的测试用例中，我使用的是 example-image ，而不是该警告标志-a 来自 mwe 包，这样您就可以轻松运行该示例，而无需下载任何其他文件

这是代码：

\documentclass[11pt]{book}
\usepackage[default]{opensans}
\usepackage{alltt}
\usepackage[listings,skins,most]{tcolorbox}
\usepackage{xcolor}
\usepackage{graphicx}

\definecolor{WarningBoxBg}{HTML}{000000}
\newtcolorbox{WarningBox}[1][]{%
  enhanced,
  boxsep=8pt,
  colback=white,
  colframe=WarningBoxBg,
  boxrule=0.25pt,
  leftrule=35pt,
  overlay unbroken and first ={%
    \node[rotate=0,
          anchor=center,
          minimum width=1cm,
          font=\Large\sffamily\bfseries,
          xshift=17.5pt,
          white]
          at (frame.west) {%
            \includegraphics[width=11mm]{example-image-a}
    };
  }
}

\begin{document}
\begin{WarningBox}
  This is my warning message!
  \begin{itemize}
  \item line-01
  \item line-02
  \item line-03
  \item line-04
  \item line-05
  \end{itemize}
\end{WarningBox}
\end{document}

有什么方法可以删除仅内部框架（包括项目列表的框架）的圆角，并且仅在其西（左）侧这样做？

提前致谢。
