如何将方括号变成花括号？

Question

我正在使用森林环境绘制系统/树。这是我正在绘制的树。树中有五个括号。但是，我想将第一个方括号（包含 AGÊNCIA 和 TIPO DE PROCESSO 的方括号）变成花括号。可以吗？如何做？

\documentclass{article}
\usepackage{forest}
\begin{document}
\begin{forest}
        for tree={
            edge path={
                \noexpand\path[\forestoption{edge}](!u.parent anchor) -- +(5pt,0) |- (.child anchor)\forestoption{edge label};},
            grow=0,
            reversed, 
            parent anchor=east,
            child anchor=west, 
            anchor=west,
            %if n children=0{tier=word}{} 
        }
        [\textsc{oração}
        [\textsc{agência}]
        [\textsc{tipo de processo}
        [material
        [transformativo
        [resultativo]
        [não-resultativo]
        ]
        [criativo]
        ]
        [mental]
        [relacional
        [atributivo]
        [identificador]
        ]
        ]
        ]
    \end{forest}
\end{document}

像这样？

可能并不完美，但对我来说相当接近了 ;-)

\documentclass{article}
\usepackage[edges]{forest}
\begin{document}
\begin{forest}
    for tree={
        grow=0,
        reversed,
        parent anchor=east,
        child anchor=west,
        anchor=west,
if level=1{edge={rounded corners}}{},
        edge path={
            \noexpand\path[\forestoption{edge}](!u.parent anchor) -- +(5pt,0) |- (.child anchor)\forestoption{edge label};},
        calign=edge midpoint,
        }
[\textsc{oração}
    [\textsc{agência},]
    [\textsc{tipo de processo}
        [material
            [transformativo
                [resultativo]
                [não-resultativo]
            ]
        [criativo]
        ]
        [mental]
        [relacional
            [atributivo]
            [identificador]
        ]
    ]
]
    \end{forest}
\end{document}
