Center slide header in middle of revealjs Quarto

Question

I would like to center a slides header in the middle of the slide. It should actually look the same as in the title slide. I tried using {.center}, but that only centers vertically and not horizontally. Here is some reproducible code:

---
title: "Center slide in middle"
format: revealjs
---

## Slide {.center}

Output:

As you can see it is vertically centered but not horizontally. So I was wondering if anyone knows how to center the slide header in the middle of a slide in revealjs Quarto?
