    Create a dialog window displaying a title, a message, and a set of buttons which trigger callback functions.

    let d = new Dialog({
    title: "Test Dialog",
    content: "<p>You must choose either Option 1, or Option 2</p>",
    buttons: {
    one: {
    icon: '<i class="fa-solid fa-check"></i>',
    label: "Option One",
    callback: () => console.log("Chose One")
    },
    two: {
    icon: '<i class="fa-solid fa-xmark"></i>',
    label: "Option Two",
    callback: () => console.log("Chose Two")
    }
    },
    default: "two",
    render: html => console.log("Register interactivity in the rendered dialog"),
    close: html => console.log("This always is logged no matter which option is chosen")
    });
    d.render(true);
