Cannot create footnote without marker

Question

I am using this template https://www.overleaf.com/latex/templates/aaai-2023-author-kit/wxnmhzcrjbpc and would like to remove the marker to my footnote.

I tried using the code from Footnote without a marker to remove the marker but it still did not work. You can see below that the "footnote without marker" still has the marker.

\makeatletter
\newcommand\blfootnote[1]{%
  \begingroup
  \renewcommand{\@makefntext}[1]{\noindent\makebox[1.8em][r]#1}
  \renewcommand\thefootnote{}\footnote{#1}%
  \addtocounter{footnote}{-1}%
  \endgroup
}
\makeatother

I cannot post a MWE here because there are several other files but here is the editable MWE https://www.overleaf.com/6147694589pmbfyhnqdrcy

Here is the MWE that I can post.

I believe that the marker is \@thefnmark. You might try locally defining it to be empty. — rallg, Mar 15 '23 at 18:43
@rallg how do i do that. Do you have a code that I can copy paste? — Kong, Mar 15 '23 at 19:07
You could try the solutions by @Simon Dispa to my similar question, they work for me in my documents, hopefully they can help too — JamesT, Mar 15 '23 at 19:20

I use a different (custom) document class, so my code may not be entirely correct for the question. But this works in my custom class, so something similar should work for you:

The footnote marker is placed by \@thefnmark, which is in LaTeX base document classes. In the document body

This text has normal footnotes, with marker.
\begingroup%
\makeatletter\def\@thefnmarker{}\makeatother%
This text would have an empty footnote marker.
\endgroup%
This text has normal footnote marker. You may need to subtract 1 from the marker count.

Note the use of percent at the end of the code lines. That prevents extra paragraph breaks.

An alternative approach is to define two kinds of footnotes, using different macros. One kind has \@thefnmarker as part of its definition, and the other kind does not.
