如何在 \maketitle 命令中将 prop_map_function 替换为 prop_map_inline

Question

我有一个代码，可以自动标记 \maketitle 命令的所有字段。此代码通过 \prop_function 进行迭代，但我想通过 prop_map_inline 进行迭代，以减少代码量，但我收到错误：您不能使用带有“字符 @”的前缀。感谢大家的帮助。

\documentclass{article}
\usepackage{tagpdf}
\tagpdfsetup{tabsorder=structure,uncompress,activate-all,add-new-tag=Title/P,interwordspace=true,tagunmarked=false,log/all}
\pagestyle{empty}
\ExplSyntaxOn

    @thanks = H1 ,
    @title  = H1 ,
  }
\DeclareRobustCommand\thanks[1]{\footnotemark
    \protected@xdef\orig@@thanks{\orig@@thanks
        \protect\footnotetext[\the\c@footnote]{#1}}}
