将Font Awesome图标添加到可视化作曲家

I'm trying to add an icon picker that allows users to select Font Awesome 5 icons.

This code works but displays Font Awesome 4.7 icons (included in visual composer plugin), I already tried to set "Fontawesome 5 Free" as type and value, but no icons displayed.

array(
                    'type' => 'iconpicker',
                    'heading' => __( 'Icon', 'js_composer' ),
                    'param_name' => 'icon_fontawesome',
                    'value' => '',
                    'group' => 'General',
                    'settings' => array(
                        'emptyIcon' => false,
                        'type' => 'fontawesome',
                        'iconsPerPage' => 4000,
                    ),
                    'dependency' => array(
                        'element' => 'type',
                        'value' => 'fontawesome',
                    ),
                    'description' => __( 'Select icon from library.', 'js_composer' ),
                    'group' => 'Content',
                ),

I want to include font awesome 5 icons.
