Dashboard 2.0 : change top bar color on mobile?

Hi,

I'm trying to change this in Dashboard 2.0. I tried adding <meta name="theme-color" ...> to a global template (widget UI-scoped, as it usually works) but it has no effect.

It's probably because Dashboard 2.0 already sets it :

<!-- Auto light and dark mode switching of status bar -->
<meta name="theme-color" media="(prefers-color-scheme: dark)" content="#111">
<meta name="theme-color" media="(prefers-color-scheme: light)" content="white">

How could I change or overwrite that ?

Thanks a lot
