How do I refer to existing footnotes inside a caption?

I have a footnote in my latex text that that I am reusing a lot. This article on texfaq.org helped me how to do that. However, sometimes I need to refer to the same footnote within, e.g., a figure caption. Latex document example:

usepackage[utf8]{inputenc}
usepackage[T1]{fontenc}
usepackage{graphicx}
usepackage{hyperref}
usepackage{footmisc}
usepackage{lipsum}

begin{document}
section*{My text}

Here is textfootnote{Footnote: blahdots} 
Here is more textfootnote{label{fn:info} Footnote: blah blahdots}

begin{figure}[h]
    centering
    includegraphics[width=0.4linewidth]{example-image-a}
    % caption{Important remarkfootref{fn:repeat}} %% With footref
    caption{Important remarkfootnotemark[ref{fn:info}]} %% With footnoteremark
    label{fig:example-image-a}
end{figure}

end{document}

This seems to not work that great. Using footnoteremark yields:

Argument of @caption has an extra }.

If I try using a footref (using the "footmisc" package), I get:

Missing endcsname inserted.

Comment in/put the "caption" lines in the example to see the different outputs. How can I use any of these commands inside captions? If I had to choose, I’d prefer an answer for footref, as I found that to be neater. Thanks.
