Essential Addons for Elementor - Filterable Gallery widget fields not translatable

Overview of the issue

When using the Essential Addons for Elementor's Filterable Gallery widget with WPML,  the following fields; eael_fg_control, eael_fg_gallery_item_name, eael_fg_gallery_control_name, eael_fg_gallery_item_video_link, fg_item_cat fields cannot be translated.

Workaround

Add the following XML in WPML > Setting > Custom XML Configuration:

<wpml-config>
   <elementor-widgets>
      <widget name="eael-filterable-gallery">
         <fields-in-item items_of="eael_fg_gallery_items">
            <field type="Filterable Gallery: eael_fg_gallery_item_name" editor_type="LINE">eael_fg_gallery_item_name</field>
            <field type="Filterable Gallery: eael_fg_gallery_control_name" editor_type="LINE">eael_fg_gallery_control_name</field>
            <field type="Filterable Gallery: Item Link" editor_type="LINK">eael_fg_gallery_item_video_link</field>
            <field type="Filterable Gallery: Item Category" editor_type="LINE">fg_item_cat</field>
         </fields-in-item>
         <fields-in-item items_of="eael_fg_controls">
            <field type="Filterable Gallery: Category" editor_type="LINE">eael_fg_control</field>
         </fields-in-item>
      </widget>
   </elementor-widgets>
</wpml-config>
 

Then apply a small edit to the post for these new fields to load in the translation editor.
