How do I reorder the color styles in Figma Slides?

How do I recorder custom color styles in Figma Slides?

In Figma Design, I can click on the background outside of any frame, see a list of the color styles in the right side bar, and rearrange their order.

However in Figma Slides, when I click on the background outside of any frame, I don’t see any color styles in the right side bar.
