Set cookies (using Window event):

    private void DemoWindow_FrameLoadStart(object sender, FrameLoadStartEventArgs e)
    {
        var cookieManager = CefCookieManager.GetGlobal(null);

        var names = new string[] { "company", "founder", "hq"};
        var values = new string[] { "Meta", "Mark Zuckerberg", "California"};

        for (int i = 0; i < names.Length; i++)
        {
            var cookie = new CefCookie
            {
                Name = names[i],
                Value = values[i],
                Expires = DateTime.Now.AddDays(1)
            };

            cookieManager.SetCookie(@"http://app/index.html", cookie, new SetCookieCompletion());
        }
    }

Set/get cookies (using Controller class):

    [ChromelyRoute(Path = "/cookiecontroller/set")]
    public void SetCookie()
    {
        var cookieManager = CefCookieManager.GetGlobal(null);

        var names = new string[] { "country", "state", "county", "city", "zipcode" };
        var values = new string[] { "USA", "New Jersey", "Bergen County", "Saddle Brook", "07663" };

        for (int i = 0; i < names.Length; i++)
        {
            var cookie = new CefCookie
            {
                Name = names[i],
                Value = values[i],
                Expires = DateTime.Now.AddDays(1)
            };

            cookieManager.SetCookie(@"http://app/index.html", cookie, new SetCookieCompletion());
        }
    }

    [ChromelyRoute(Path = "/cookiecontroller/get")]
    public void GetCookies()
    {
        var taskCompletion = new TaskCompletionSource<bool>();
        var cookieManager = CefCookieManager.GetGlobal(null);
        var cookieVisitor = new CookieVisitor(taskCompletion);
        cookieManager.VisitAllCookies(cookieVisitor);

        taskCompletion.Task.ContinueWith(task =>
        {
            var cookies = cookieVisitor.Cookies;
            try
            {
                var scriptExecutor = _config?.JavaScriptExecutor;
                if (scriptExecutor != null)
                {
                    if (cookies != null && cookies.Any())
                    {
                        StringBuilder builder = new();
                        foreach (var cookie in cookies)
                        {
                            builder.Append($"Name: {cookie.Name} &nbsp; &nbsp; Value: {cookie.Value} <br>");
                        }

                        var cookiesStrScript = $"getCookiesResponse('{builder}')";
                        scriptExecutor.ExecuteScript(cookiesStrScript);
                    }
                    else
                    {
                        scriptExecutor.ExecuteScript("getCookiesResponse('No cookies found or error retrieving cookies');");
                    }
                }
            }
            catch (Exception e)
            {
                Logger.Instance.Log.LogError(e);
            }
        });
    }

Note:

// Note: Normal local scheme - local, does not work with setting cookies, please try http instead
// So this - 
// config.StartUrl = "local://app/index.html";
// may not work

config.UrlSchemes.Add(new UrlScheme("custom-local", "http", string.Empty, string.Empty, UrlSchemeType.LocalResource));
config.StartUrl = "http://app/index.html";
