AMS: Non-uppercase Title

[GiacomoZheng]

Hi,

I wonder if it is possible to keep the case of title. The source code of unequivocal-ams is

  align(center, upper({
    text(size: large-size, weight: 700, title)
    ...
  }))

but the upper is not an element function so we cannot use #show to ignore the upper.

Is it possible to provide an option? Or is there any magic I can use?

PS: in latex, we can use

\let\origmaketitle\maketitle
\def\maketitle{
  \begingroup
  \def\uppercasenonmath##1{} % this disables uppercasing title
  \let\MakeUppercase\relax % this disables uppercasing authors
  \origmaketitle
  \endgroup
}
