Change child item background color in an accordion

I am trying to change the white background of the expanded accordion item on this Accordion. Going to “Accordion item nested styles” and changing the background color there only changes the color of the header (which I’ve already done). I don’t see where to change this. I also cannot find a doc for it either.

In the Accordion settings, set the “Bordered” prop to false to see background color changes on the accordion body. For more details, refer to the Antd5 Accordion documentation.
