使用 rmarkdown 进行日期投影仪大都市

Question

我正在尝试制作一个带有 Metropolis 主题的投影仪演示文稿。我调整了颜色，如下所示：

    output: 
        beamer_presentation:
            latex_engine: xelatex
            theme: "metropolis"
            slide_level: 3
    navigation: horizontal 
    classoption: "aspectratio=169"
    header-includes:
         - \metroset{block=fill}
         - \useoutertheme{infolines}
         - \usepackage{xcolor}
         - \definecolor{GreenM}{RGB}{107, 169, 36}
         - \definecolor{BlueM}{RGB}{6, 48, 96}
         - \setbeamercolor{title}{fg=BlueM}
         - \setbeamercolor{title separator}{fg = GreenM}
         - \setbeamercolor{author}{fg=BlueM}
         - \setbeamercolor{date}{fg=BlueM}
         - \setbeamercolor{progress bar in section page}{fg = GreenM,bg = gray}
 
         - \setbeamercolor{frametitle}{bg=GreenM, fg = white}
         - \setbeamercolor{normal text}{fg=BlueM}
         - \setbeamercolor{structure}{fg=BlueM}
         - \setbeamercolor{item}{fg=GreenM}
         - \setbeamercolor{block title alerted}{fg=red}
         - \setbeamercolor{section in head/foot}{fg=BlueM, bg=white}
         - \setbeamercolor{subsection in head/foot}{fg=white,bg=BlueM}
         - \setbeamercolor{author in head/foot}{fg=BlueM}
         - \setbeamercolor{date in head/foot}{fg=white, bg=BlueM}
         - \setbeamertemplate{page number in head/foot}{}

现在日期显示为 2022/2023。我想在标题幻灯片和页脚中将其设置为“2023 年 5 月 27 日”（不是今天的日期）。我正在使用 Rmarkdown 制作此演示文稿。有人知道我该怎么做吗？

尝试\AtBeginDocument{\date{May 27, 2023}}在标题中包含：
