I am trying to create a footnote symbol * in a tcolorbox environment and the result is not the symbol nor at the bottom of the page instead within the box!

\usepackage[most]{tcolorbox}
\usepackage[symbol]{footmisc}

\begin{document}
\begin{tcolorbox}[colback=yellow!20!white,colframe=green!40!gray]
\color{green!40!gray}{\large {\bf Definitions}}\color{black} \ \ \ {\bf 
Strategy 
for Sketching Graphs}\footnote[1]{This strategy is refined further, for 
rational 
functions, in Section 2.3.}

\begin{enumerate}
\item[{\bf a)}]
\item[{\bf b)}]
\item[{\bf c)}]
\item[{\bf d)}]
\item[{\bf e)}]
\item[{\bf f)}]
\end{enumerate}

\end{tcolorbox}
\end{document}

This outputs:

First of all tcolorbox is not reading the correct symbol for '1' in the footmisc package nor is the footnote at the bottom of the page. Please advise!

You may use the \footnotemark and \footnotetext macros:

\documentclass{article}

\usepackage{enumitem}

\usepackage[most]{tcolorbox}
\usepackage[symbol]{footmisc}

\begin{document}
\begin{tcolorbox}[colback=yellow!20!white,colframe=green!40!gray]
    \textcolor{green!40!gray}{\large \textbf{Definitions}}
    \quad\textbf{Strategy for Sketching Graphs}\footnotemark[1]

    \begin{enumerate}[label=\textbf{\alph*)}]
        \item
        \item
        \item
        \item
        \item
        \item
    \end{enumerate}

\end{tcolorbox}
\footnotetext[1]{This strategy is refined further, for 
    rational functions, in Section 2.3.}
\end{document}
