Going to a page during WillEnterforeground in xamarin

Question

I am working on a different iOS app that is built on Xamarin App. I have a requirements that when an app is idle and the user open his app again he will redirect to login page if his session is expired. Is there a way to redirect to a login page in Xamarin in the WillEnterForeground event AppDelegate?

public async override void WillEnterForeground(UIApplication uiApplication)
    {
        var msalService = new MsalAuthService();
        var isUserCurrentlyLogin = await  msalService.IsCurrentlyLogIn();

        if (!isUserCurrentlyLogin)
        {
            // Go To Login Page

        }
        else
        {
            // stay on the current page
        }

        base.WillEnterForeground(uiApplication);
    }
