Changing the size of the mathfont, except for the numbers

Question

I need to use Tex Gyre Adventor as a font in my documents. This font has no math font, so I'd like to use the numbers of that font in math mode.
I managed to do it using \setmathfont[range=up/{num}]{TeX Gyre Adventor}, as indicated in the documentation of unicode-math.

My problem is that the numbers in math mode are bigger than the letters. Here is below an example.

\documentclass{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Adventor}
\setmathfont{xits-math}
\setmathfont[range=up/{num}]{TeX Gyre Adventor}
\begin{document}
In text mode: 3\,z.

In math mode: $3\,z$.
\end{document}

Is there any way to change the size of the xits font only, so it has the same size as the Tex Gyre Adventor font ?

Thank you,
Régis

I'm sorry, I found the solution on this very site : https://tex.stackexchange.com/a/210074/63033

I post it here in case anyone is interested :

\documentclass{article}
\usepackage{fontspec}
\usepackage{unicode-math}
\setmainfont{TeX Gyre Adventor}
%\setmathfont{xits-math}
\setmathfont[Scale=1.2]{xits-math}
\setmathfont[range=up/{num}]{TeX Gyre Adventor}
\begin{document}
In text mode: 3z

In math mode: $3z$.
\end{document}

I just had to had the Scale parameter to \setmathfont{xits-math}.
