Zoom in/out on Click

Hello Yes, it’s possible. I can provide a sample, but one question. Click on what?

You can try this code inside the custom js section, it zooms the book after double click event on the book container

const instance = this;
const $ = jQuery;
let index = 0;
const zoom = [1, 2];

instance.$container.on('dblclick', (e) => {
    index = index == 0 ? 1 : 0;
    instance._setZoom({zoom:zoom[index]}, true, false);
});
