Can't use \PassOptionsToClass in beamer by cls document

Question

The MWE:

% test.tex
\documentclass{format}
\begin{document}
\begin{frame}
  My name is chichi.
\end{frame}
\end{document}

my .cls file:

% format.cls
\PassOptionsToClass{20pt,aspectratio = 1610}{ beamer }
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{format}[23/06/2023]
\LoadClass{beamer}

However, if I use \PassOptionsToClass directly in .tex file, it will be useful, like this:

\PassOptionsToClass{20pt,aspectratio = 1610}{beamer}
\documentclass{beamer}
\begin{document}
\begin{frame}
  My name is chichi.
\end{frame}
\end{document}

Because I want to design a user interface that changes the beamer size and font size in beamer template, I use \PassOptionsToClass in the .cls file.

Modify the .cls to:

% format.cls
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{format}
\PassOptionsToClass{20pt,aspectratio = 1610}{beamer}
\ProcessOptions\relax
\LoadClass{beamer}

Thank you very much for your help, and I found that the \PassOptionsToClass command does not use spaces for the Class, which I added to the code for aesthetics. – user1159339 Jun 23 '23 at 07:02
@user1159339 You should always be careful with extra spaces and even end of lines (unless you are in expl3 context). – cabohah Jun 23 '23 at 08:05
