Acronym package: custom list of acronyms which maintains backreferencing

I’m using the acronym package for my thesis, and I’d like to create the list of acronyms manually to allow for a more sophisticated formatting, namely upper case in list, lower case in document. I’ve already tried this alternative solution here, but it rendered the commands Ac, Acf, etc. (start acronym with capital letter) dysfuntional.

Crucially, I still want acronyms in the text to reference back to the list.

Here´s a first step. Clearly, the backreferencing doesn’t work:

documentclass[]{article}

usepackage{hyperref}
usepackage{acronym}
acrodef{AI}{artificial intelligence}
    
begin{document}

section*{List of Acronyms}
How to do this manually, and yet enable backreferencing from text?
begin{description}
    item[AI] Artificial Intelligence
end{description}

section{Acronym test}
First mention of acronym: ac{AI}. Second mention of acronym: ac{AI}.

end{document}

I appreciate any ideas on how to create such a custom list. The documentation has not been very helpful.. https://www.texlive.info/CTAN/macros/latex/contrib/acronym/acronym.pdf

documentclass{article}
usepackage[acronym]{glossaries}

% Add glossaries
makeglossaries % <-- This is required to build the glossaries

% 1st param: ID of the acronym
% 2nd param: Actual acronym
% 3rd param: Long version of the acronym
newacronym{AI}{AI}{artificial intelligence}

begin{document}
section{Acronym test}
First mention of acronym: gls{AI}. Second mention of acronym: gls{AI}. Forced long version of acronym: acrlong{AI}.
