% definition of a new tcolorbox whic uses the style:

First option: using a style directly:
\begin{tcolorbox}[mybeautiful,title=Method]
\begin{minipage}{0.45\textwidth}
\begin{itemize}
\item I hope
\item this is
\item what you want
\end{itemize}

\item this is

Second option (more convenient) a new tcolorbox:
