如何将家谱树中的线条样式更改为箭头？

在浏览 genealogytree 包时，我找不到箭头这样的线条样式。我不知道在 genealogytree 选项中传递键的想法。这是一个 MWE

\documentclass{article}
\usepackage[all]{genealogytree}
\tcbset{male/.style={colframe=red,sharp corners},female/.style={colframe=blue,rounded corners}}
\begin{document}
\begin{tikzpicture}
\genealogytree[template=signpost,male={red},female={blue}]{ parent{
        g[male]{first child}
        c[female]{second child}
        c[female]{third child}
        p[male]{father}
        p[female]{mother}
}}
\end{tikzpicture}
\end{document}

下面是在黄色背景上将边缘绘制为蓝色箭头的示例：

\documentclass{article}
\usepackage[all]{genealogytree}
\tcbset{male/.style={colframe=red,sharp corners},female/.style={colframe=blue,rounded corners}}
\begin{document}
\begin{tikzpicture}
\genealogytree[
    template=signpost,
    male={red},
    female={blue},
    edges={foreground={blue, thick,->},background={yellow, very thick}}
    ]{ parent{
        g[male]{first child}
        c[female]{second child}
        c[female]{third child}
        p[male]{father}
        p[female]{mother}
}}
\end{tikzpicture}
\end{document}

请查看手册的第 8.3 节。
