How do I obtain the preview image for a PDF?

I have a SwiftUI view of the form

struct ContentView: View {
    // ...
    
 .onDrop(of: [.pdf], isTargeted: $isDropTargeted) { pdfs in
            for pdf in pdfs {

I'm just not sure what to do next, I see there's a loadPreviewImage() that if I use like:

  Task.detached {
                    // returns any NSSecureCoding object
                    let image  = try! await pdf.loadPreviewImage()
                }

Not sure how I'm supposed to get my preview image from that NSSecureCoding object
