I am new to the thanks command. I was trying to add the funding for two authors and I used something like
\newcommand*\samethanks[1][\value{footnote}]{\footnotemark[#1]}
\author{First Author\thanks{Supported by some funding}}
\author{Second Author\samethanks}
and it seems there is a very ugly hyperlink box and after some search I couldn't find a way to get rid of it. Also I am not sure if the way I used to add thanks to both authors is correct. Thank you in advance for any suggestion and advice.

\footnotemarkand\footnotetextinstead of the first\thanks. See page 48 of hyperref manual. – John Kormylo Nov 26 '20 at 17:27
