How to suppress symbol for LaTeX footnote
There are many solutions online, for example this Stack Exchange post. The one that worked for me is as follows:
\documentclass{article}
%write the following immediately after documentclass{} if possible.
\makeatletter
\def\blfootnote{\gdef\@thefnmark{}\@footnotetext}
\makeatother
Subsequently, you can then use the \blfootnote command to write a footnote without any symbol (no asterisk, no star, etc.)
