如何在“图形”索引后用句号替换分号？

Question

我正在按照 IEEE 访问模板中定义的通用格式编辑一份背面纸质草稿。现在，整体图形索引的颜色符合 IEEE 访问模板，但每个“图形”索引后的分号不正确，应将其替换为句号。此外，子图标题的索引颜色应该是黑色，但现在它们都是“accessblue”。我该如何设置它们？

这是我目前使用的包的代码：

\documentclass{ieeeaccess}
\usepackage{cite}
\usepackage{amsmath,amssymb,amsfonts}
\usepackage{algorithmic}
\usepackage{graphicx}
\usepackage{textcomp}
%the below 5 lines of code are extra packages I referenced in addition to the original IEEE access template packages used
\usepackage{caption}
\usepackage{subcaption}
\captionsetup{font={sf,small,stretch=0.80},labelfont={bf,color=accessblue}}
\usepackage{tabularx}
\usepackage{booktabs}


\usepackage{bm}

下面是一个带有子图的示例，展示了我如何插入图形：

\begin{figure}
    \centering
    \begin{subfigure}{0.48\textwidth}
        \centering
        \includegraphics[width=\linewidth]{Figures/subfig1.pdf}
        \caption{Description.}
        \label{fig:sub1}
    \end{subfigure}
    
    \vspace{10pt} % Adjust vertical spacing between subfigures
    
    \begin{subfigure}{0.48\textwidth}
        \centering
        \includegraphics[width=\linewidth]{Figures/subfig2.pdf}
        \caption{Description.}
        \label{fig:sub2}
    \end{subfigure}
    
    \caption{\textbf{Description.}}
    \label{label}
\end{figure}
