Footnote in Figure Caption

[sarkrui]

Has anyone managed to add footnote inside the caption of a figure?

I have tried footnotemark with footnotetext The footnote will be added one page before where's actually referred.

\begin{figure}[!ht]
    \centering
    \includegraphics[width=3in]{example-image-a}
    \caption{A radar chart\protect\footnotemark Hello world, this is a caption.}
    \label{fig:helloworld}
\end{figure}
\footnotetext{The style referred to:https://google.com}

Thanks.
