Accessing an environmentvariable from a SwiftUI func

I've got a SwiftUI app that uses two separate web views to display html pages stored in a CoreData database. When the user clicks on a link in one web view, the linked file is shown in the second web view. To make this happen I'm using the following:

struct LibCompWebView: UIViewRepresentable {
    let request: URLRequest
    func makeCoordinator() -> Coordinator {
        .init(self)
    }

    func makeUIView(context:Context) -> WKWebView {
        let webView = WKWebView()
        webView.navigationDelegate = context.coordinator
        return webView
    }

    func updateUIView(_ webView: WKWebView, context: Context) {
        webView.load(request)
    }

    class Coordinator: NSObject, WKNavigationDelegate {
        var webView: LibCompWebView
        init(_ webView:LibCompWebView) {
            self.webView = webView
        }

        func webView(_ webView: WKWebView, decidePolicyFor navigationAction: WKNavigationAction, decisionHandler: @escaping (WKNavigationActionPolicy) -> Void) {
            if navigationAction.navigationType == .linkActivated {
navigateLibCompTo(theURL:navigationAction.request.url!)
                decisionHandler(.cancel)
            } else {
                print("not a user click")
                decisionHandler(.allow)
            }
        }
    }
}

In that NavigationDelegate is a call to a function called navigateLibCompTo, which passes the URL that the user clicked on to a function that is then supposed to look up the appropriate stuff from my coredata entity and load it into the appropriate web view.

I'm sharing my CoreData stuff as a StateObject accessed through an @environmentobject. The problem is that my navigateLibComp function is outside of my view hierarchy, so I have no way to access the CoreData stuff.

I'm completely stumped!
