public static async Task<string> SignOut(){
    IEnumerable<IAccount> accounts = await App.IdentityClientApp.GetAccountsAsync();

    graphClient = null;
    TokenForUser = null;
    return "";
}
public class LogoutHelper : ILogoutHelper
{
    public void LogoutSSO()
    {
        CookieManager.Instance.RemoveAllCookies(null);
        CookieManager.Instance.RemoveAllCookie();
        CookieManager.Instance.RemoveSessionCookie();
        CookieManager.Instance.Flush();
        Device.BeginInvokeOnMainThread(() => new Android.Webkit.WebView(null).ClearCache(true));
    }
}
