Screenshot of WebView gives just white

I'm trying to take a screenshot of WebView. I have successfully done it when I'm displaying it on the screen but the goal is to not need this but just take the screenshot. Right now this code just gives white even though Text component is working correctly. I believe it could be something with website not having time to load but I'm not sure what is the solution.

Code Block swiftimport SwiftUI
import CoreData
extension View {
  func takeScreenshotView(rect: CGRect) -> UIImage {
    let window = UIWindow(frame: rect)
    let hosting = UIHostingController(rootView: self)
    window.rootViewController = hosting
    window.makeKeyAndVisible()
    return hosting.view.setImage(rect: rect)
  }
}
struct ContentView: View {
  @State var image: UIImage?
   
  var body: some View {
    VStack {
      Button("Snap") {
        print("take screenshot")
        image = WebView(url: "https://lankinen.xyz").takeScreenshotView(rect: CGRect(x: 0, y: 0, width: 100, height: 100))
//        image = Text("hello world").takeScreenshotView(rect: CGRect(x: 0, y: 0, width: 100, height: 100))
      }
      if image != nil {
        Image(uiImage: image!)
      }
    }
    .padding()
    .background(Color.green)
  }
}

Code Block swift
import SwiftUI
import CoreData

extension View {
func takeScreenshotView(rect: CGRect) -> UIImage {
let window = UIWindow(frame: rect)
let hosting = UIHostingController(rootView: self)
window.rootViewController = hosting
window.makeKeyAndVisible()
return hosting.view.setImage(rect: rect)
}
}

struct ContentView: View {
@State var image: UIImage?

var body: some View {
VStack {
Button("Snap") {
print("take screenshot")
image = WebView(url: "https://lankinen.xyz").takeScreenshotView(rect: CGRect(x: 0, y: 0, width: 100, height: 100))
// image = Text("hello world").takeScreenshotView(rect: CGRect(x: 0, y: 0, width: 100, height: 100))
}
if image != nil {
Image(uiImage: image!)
}
}
.padding()
.background(Color.green)
}
}
