How can I hightlight text with pdfkit pdfview

Question

I use pdfkit and I want to customize the menu contents of the selected text that appears. When I long-press and select the text, the system menu pops up with the highlight option, and nothing happens when I click on highlight. I want to customize the menu and replace the highlight copy and other options on the current system.

My code implementation:

class MyPDFVC: UIViewController, PDFViewDelegate {

let pdfView = PDFView()

override func viewDidLoad() {
    super.viewDidLoad()
    
    pdfView.frame = CGRect(x: 0, y: 0, width: 
    self.view.frame.width, height: self.view.frame.height)
    pdfView.isUserInteractionEnabled = true
    pdfView.delegate = self
    self.view.addSubview(pdfView)
    
    //加载的 PDF 文件
    if let pdfURL = Bundle.main.url(forResource: "SPR-pdf", withExtension: "pdf"), let pdfDocument = PDFDocument(url: pdfURL) {

        pdfView.document = pdfDocument
        pdfView.goToFirstPage(nil)
    }
}

}
