Deeplinking to swift app when app is closed - swift

Question

I am working on adding deep linking to my app so that the app will go to a separate page when launched through a deep link. This code that I have so far works perfectly the only issue is that it dosen't work when the app is closed. Is there any way to make this code work when the app is not already running? Thanks for any help in advance!
import UIKit
class SceneDelegate: UIResponder, UIWindowSceneDelegate {
var window: UIWindow?
func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
// Use this method to optionally configure and attach the UIWindow `window` to the provided UIWindowScene `scene`.
// If using a storyboard, the `window` property will automatically be initialized and attached to the scene.
// This delegate does not imply the connecting scene or session are new (see `application:configurationForConnectingSceneSession` instead).
guard let _ = (scene as? UIWindowScene) else { return }
}
func sceneDidDisconnect(_ scene: UIScene) {
// Called as the scene is being released by the system.
// This occurs shortly after the scene enters the background, or when its session is discarded.
// Release any resources associated with this scene that can be re-created the next time the scene connects.
// The scene may re-connect later, as its session was not necessarily discarded (see `application:didDiscardSceneSessions` instead).
}
func scene(_ scene: UIScene, openURLContexts URLContexts: Set<UIOpenURLContext>) {
if let url = URLContexts.first?.url{
print(url)
let urlStr = url.absoluteString

func sceneDidBecomeActive(_ scene: UIScene) {

// Use this method to restart any tasks that were paused (or not yet started) when the scene was inactive.
}

// Called when the scene will move from an active state to an inactive state.
// This may occur due to temporary interruptions (ex. an incoming phone call).

// Called as the scene transitions from the background to the foreground.
// Use this method to undo the changes made on entering the background.
