Be careful, this is discouraged for a reason, it can lead to unexpected results, see this answer for some details. — schtandard, Nov 27 '23 at 21:21

Should work out of the box with LuaLaTeX and XeLaTeX

\documentclass[a4paper]{article}
\NewDocumentCommand{\μinv}{}{text}
\begin{document}
 \μinv
\end{document}

pdfLaTeX on the other hand is not really set up for this, and I wouldn't recommend it.
