How to set the second and subsequent appearances of an acronym using acro package

Question

I'm using the acro package for my acronyms. My supervisor didn't like the use of ancronyms in the text, so I have to put all of them in the long form, but keeping the first style like "acronym (AC)" and the rest of uses "acronym". How can I configure the acro package for to print the long form in the second and subsequent uses?

\documentclass{article}
\usepackage{acro}
\DeclareAcronym{TIAE}{
short=TIAE,
long=this is an example,
}
\begin{document}
Firt use \ac{TIAE},
then second use \ac{TIAE},  %<--- must be "this is an example"
third use \ac{TIAE} and     %<--- must be "this is an example"
last use \ac{TIAE}.\par     %<--- must be "this is an example"
%
\printacronyms
\end{document}

Answer 1

You could create a macro which contains \acifused to test if the acronym was already used and use \acl if true and \ac if false:

\documentclass{article}
\usepackage{acro}
\DeclareAcronym{TIAE}{
short=TIAE,
long=this is an example,
}
\newcommand{\myac}[1]{\acifused{#1}{\acl{#1}}{\ac{#1}}}
\begin{document}
Firt use \myac{TIAE},
then second use \myac{TIAE},  %<--- must be "this is an example"
third use \myac{TIAE} and     %<--- must be "this is an example"
last use \myac{TIAE}.\par     %<--- must be "this is an example"
%
\printacronyms
\end{document}
