I am using SwiftUI with SpriteView. How can I make the SwiftUI background transparent so that it keeps appearing the SpriteView content behind?

I have a scene in SpriteKit and I call it through SpriteView and I'm using SwiftUI to make a header with some information. I've already managed to make the layout I want it to have, but I can't make the header without a background (transparent). I want the background of this header to be transparent so that only the elements I set in SwiftUi appear and the background is the continuation of the SpriteView.
