WKWebView -How to AutoPlay Video Without VideoID?

In my app I use WKWebView and the user can go to different websites like google, wikipedia, vimeo, etc. The issue is if the user decides to go to https://www.youtube.com, when the user taps a thumbnail to play it, it doesn't autoplay because I don't have the videoId (eg. "https://youtu.be/MpvshzR6tNk"), I just have the the youtube website url

For example:

func loadRequest() {

    let strThatUserEntered = "https://youtube.com"

    let urlStr = "strThatUserEntered"
    guard let url = URL(string: urlStr), let request = URLRequest(url: url) else { return }
    wkWebView.load(request)
    wkWebView.allowsBackForwardNavigationGestures = true
}

Now when the user selects a random thumbnail, the video loads, the youtube play button appears, and when it's pressed, I get: An error occurred, please try again later (this video definitely works)

How can I enable autoplay on any selected youtube thumbnail , if I don't have the videoID?

code:

override func viewDidLoad()
    super.viewDidLoad() 

    let webConfiguration = WKWebViewConfiguration()
    webConfiguration.allowsInlineMediaPlayback = true
    webConfiguration.mediaTypesRequiringUserActionForPlayback = []
    
    wkWebView = WKWebView(frame: .zero, configuration: webConfiguration)
    wkWebView.navigationDelegate = self
    wkWebView.uiDelegate = self
    
    // pin wkWebView anchors to screen

    loadRequest()
}
