在latex中，如何使甘特图中的所有WBS活动左对齐？

\usepackage{pgfgantt}

\begin{ganttchart}[
    hgrid,
    vgrid,
    x unit=0.5cm,
    y unit title=0.6cm,
    y unit chart=0.8cm,
    bar height=0.4,
    bar top shift=0.2,
    group right shift=0,
    group top shift=0.4,
    group height=0.2,
    group peaks width=0.2,
    inline,
    time slot format=isodate,
    time slot unit=day,
    compress calendar
]{2022-01-01}{2022-12-31}

\ganttbar[bar/.append style={align=left}]{WBS活动1}{2022-01-01}{2022-01-31} \\
\ganttbar[bar/.append style={align=left}]{WBS活动2}{2022-02-01}{2022-02-28} \\
% 添加更多的 WBS 活动

\end{ganttchart}
