更改 tcolorbox 中的内联方程点大小

Question

我们正在尝试将内联和显示方程式字体大小更改为 10pt，它适用于显示方程式，但对内联数学不起作用，请提供建议，如何更改内联数学方程式点大小？

请查找 MWE 文件：

\documentclass{book}
\usepackage{amsmath}
\usepackage[most]{tcolorbox}

\newenvironment{boxtype1}
{%
\everymath{\fontsize{12bp}{14bp}\selectfont}
\everydisplay{\fontsize{12bp}{14bp}\selectfont}
\begin{tcolorbox}[fontupper=\fontsize{10bp}{12bp}\selectfont\sffamily]}
{\end{tcolorbox}}

\makeatother
