在自定义 Beamer 模板的 Section Heading 下获取点

Question

ua-theme我正在使用Nico Schlomer的修改版本。

https://github.com/nschloe/ua-beamer/blob/master/theme/beamerouterthemeUniversiteitAntwerpen.sty

使用该帖子：

进度条主题上的导航栏太长，可以换行吗？

我能够获得换行到多行的章节标题。

我想在章节标题下获得点：

这是一个简单的例子：

我有以下名为“beamerouterthemeUniversityCustom.sty”的文件

我还有一个名为的文件beamerthemeUniversityCustom.sty：

\section{Section 8}

Text goes here
\end{frame}

\section{Section 9}

\begin{frame}[t]
\frametitle{Section 9}

\end{frame}

\end{document}

我认为我需要进行更改，\insertsectionnavigationhorizontal以便让点出现在章节标题下，但我无法弄清楚。有人可以帮忙吗？
