[Closed] Can't translate items of a loop inside of a loop (elementor xml)

I am trying to: Translate custom elementor widget of a theme
I already tried to add the custom xml for this but it doesn't work. I'm familiar on this works, but for loop inside of a loop I can't do it or if I split them in two different tags, it doesn't work. For instance:

<widget name="trx_sc_price">
<fields-in-item items_of="sc_price_item">
<field editor_type="LINE">title</field>
<field editor_type="AREA">detail</field>
<field editor_type="LINE">link>url</field>
</fields-in-item>
<fields-in-item items_of="sc_price_item_price">
<field editor_type="LINE">before</field>
<field editor_type="LINE">value</field>
<field editor_type="LINE">after</field>
</fields-in-item>
</widget>
sc_price_item_price is INSIDE of sc_price_item but I can't add a fields-in-item inside of another fields-in-item tag.

Link to a page where the issue can be seen: Private

I expected to see: Information available to translate on ATE

Instead, I got: Nothing related to the widget is shown on ATE
