A fancy and beautiful type of enumerate in Beamer

Question

I'm trying to reproduce the enumerate enviorment of this post (A fancy and beautiful type of enumerate) in Beamer. My MWE, adapted from there, is the following:

\documentclass{beamer}
\usepackage{tikz}
\newcommand{\Colorlist}{red,blue,green,yellow}
\newcommand{\SebastianoItem}[1]{\foreach \X[count=\Y] in \Colorlist
{\ifnum\Y=#1\relax
\xdef\SebastianoColor{\X}
\fi
}
\tikz[baseline=(SebastianoItem.base),remember
picture]{%
\node[fill=\SebastianoColor,inner sep=4pt,font=\sffamily,fill opacity=0.5] (SebastianoItem){#1)};}
}
\newcommand{\SebastianoHighlight}{\tikz[overlay,remember picture]{%
\fill[\SebastianoColor,fill opacity=0.5] ([yshift=4pt,xshift=-\pgflinewidth]SebastianoItem.east) -- ++(4pt,-4pt)
-- ++(-4pt,-4pt) -- cycle;
}}
\begin{document}
\begin{frame}
\renewcommand{\labelenumi}{\SebastianoItem{\arabic{enumi}}}
Some general advices.
  \begin{enumerate}
    \item No fast food.
    \item Don't drink to much alcohol.
    \item No pineapple on pizza. \SebastianoHighlight
    \item Don't use onions in food.
  \end{enumerate}
\end{frame}
\end{document}

When I uncomment the \renewcommand and the \SebastianoHighlight lines, the code compiles, so I guess the errors are there. I know that renewing commands in Beamer are trickier than in the Article documentclass. However, I can't find a solution. Any ideas?

Half of the problem is the Beamer does enumerate differently, and to customize the labels you should use a different command. See https://tex.stackexchange.com/a/7513/119 for example. — Willie Wong, Sep 10 '20 at 17:48

In beamer:

\setbeamertemplate{enumerate item}{\SebastianoItem{\arabic{enumi}}}

Similarly for enumerate subitem, enumerate subsubitem, and enumerate mini template.

edit file:

\documentclass{beamer}
\usepackage{tikz}
\newcommand{\Colorlist}{red,blue,green,yellow}
\newcommand{\SebastianoItem}[1]{\foreach \X[count=\Y] in \Colorlist
{\ifnum\Y=#1\relax
\xdef\SebastianoColor{\X}
\fi
}
\tikz[baseline=(SebastianoItem.base),remember
picture]{%
\node[fill=\SebastianoColor,inner sep=4pt,font=\sffamily,fill opacity=0.5] (SebastianoItem){#1)};}
}
\newcommand{\SebastianoHighlight}{\tikz[overlay,remember picture]{%
\fill[\SebastianoColor,fill opacity=0.5] ([yshift=4pt,xshift=-\pgflinewidth]SebastianoItem.east) -- ++(4pt,-4pt)
-- ++(-4pt,-4pt) -- cycle;
}}
\setbeamertemplate{enumerate item}{\SebastianoItem{\arabic{enumi}}}
\begin{document}
\begin{frame}
%\renewcommand{\labelenumi}{\SebastianoItem{\arabic{enumi}}}
Some general advices.
  \begin{enumerate}
    \item No fast food.
    \item Don't drink to much alcohol.
    \item No pineapple on pizza. \SebastianoHighlight
    \item Don't use onions in food.
  \end{enumerate}
\end{frame}
\end{document}
