How could I change the numeration style in table of contens in beamer (Latex)?

Question

Hello I am new at beamer (overleaf), so I have learned very much, so I would like to change the design of the numeration in table of contents. I mean with that (see picture attached):

I would like to change to a square, or simply the number. Anyone knows others styles? I am using the \usetheme{CambridgeUS}.

You can set the sections/subsections in toc template to change to e.g. a square or plain numbered sections:

\documentclass{beamer}
\usetheme{CambridgeUS}

\setbeamertemplate{sections/subsections in toc}[square]
%\setbeamertemplate{sections/subsections in toc}[sections numbered]

\begin{document}
    
\section{title}
\begin{frame}
    \tableofcontents
\end{frame} 
    
\end{document}
