Get current selection info from Froala editor

I am using Froala WYSIWYG editor in my project. I would like to create my own font-family select component which will display the current font-family. So I need to listen to changes of an editor's selection, each time get current font-family and update my custom component.

import "froala-editor/js/plugins/font_family.min.js";
import Froala from "froala-editor";

const editor = new Froala("#container", {
    events: {
        onSelectionChange: function() { // I need something like this.
            console.log(this.selection.get().fontFamily); // Eg. "Arial" or "Verdana". 
        }
    }
});

I only found fontFamilySelection option in the docs, however, it will show the current font family in a native editor's component. One way is to read the current font family from the native component, but it's not a very clean solution.

Is there any way to do something like this?
