3D FlipBook - How to display custom bookmarks?

Hi,

I bought your plugin and I'm trying to display custom bookmarks, what I did is:

$('.solid-container').FlipBook({
                pageCallback: function(n) {
                    return {
                        type: 'image',
                        src: `https://www.leathercode.sureskins.it/app/uploads/cataloghi/1.jpg`,
                        interactive: false
                    };
                },
                pages: 4
            });

so essentially I would like to set custom bookmarks like this:

chapter 1 chapter 2 chapter 3

when the user click on one of these, the plugin should open a specific image of the flipbook. How can I do this?

Kind regards
