Change the dependency of \maketitle command

Question

I am trying to develop a class file for my department. I want to add two dependencies to the \maketitle command. As we have \title & \author as compulsory commands for \maketitle, I want \supervisor and as we have \date which is optional, I want \subtitle. I have tried the following code. It's not working. What mistake am I committing?

\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{ML}[2020/01/24 MWE class-file]

\LoadClass{book}
\newcommand{\supervisor}[1]{\textsc{supervisor : #1}}
\newcommand{\subtitle}[1]{\textsc{}}
\renewcommand{\maketitle}{
    \makeatletter
    \thispagestyle{empty}
    \fboxsep3em
    \noindent\fbox{\begin{minipage}
            [c][\dimexpr\textheight-2\fboxsep-2\fboxrule]
            [c]{\dimexpr\linewidth-2\fboxsep-2\fboxrule}
            \begin{center}
                \bigskip
                \textbf{{\LARGE \textsc{\@title}}%\\
                    %\vspace{0.2cm}
                    %{\@subtitle}
                }
                \\
                \vfill
                {\large\textsc{\@author}}\\
                %   \vspace{0.5in}
                %   {\large \@supervisor}
                \vspace{0.5in}
                \textsc{\@date}
            \end{center}
        \end{minipage}}
        \makeatother}
