Page number of PDF in SwiftUI

I create a UIViewRepresentable to show my PDF inside my SwiftUI app. I want to access the current page number using currentPage?.pageRef?.pageNumber. from the view in which I display the pdf. How to make PDFView Created in func makeUIView(context: UIViewRepresentableContext<PDFDisplayRepresentedView>) -> PDFView Available in the view displaying the pdf so I can access its properties to obtain page number.

import SwiftUI
import PDFKit



struct PDFDisplayView: View {
    
    @Binding var pdfDocument : PDFDocument?
    
    var body: some View {
        
        PDFDisplayRepresentedView(pdfDocument: pdfDocument!)
        
    }
    
}

struct PDFDisplayRepresentedView: UIViewRepresentable {
    
    let pdfDocument: PDFDocument
    
    init(pdfDocument: PDFDocument) {
        self.pdfDocument = pdfDocument
    }
    
    
    func makeUIView(context: UIViewRepresentableContext<PDFDisplayRepresentedView>) -> PDFView {
        return createPDFViewUsing(document: pdfDocument)
    }
    
    func updateUIView(_ pdfView: PDFView, context: UIViewRepresentableContext<PDFDisplayRepresentedView>) {
        pdfView.document = pdfDocument
    }
    
    private func createPDFViewUsing(document : PDFDocument) -> PDFView {
        
        let pdfView = PDFView(frame: CGRect(x: 0, y: 0, width: 100, height: 100))
        pdfView.document = document
        ... set up pdfView attributes
        return pdfView
    }
    
    
}
