Background of the issue:
I used the EmbedPress PDF widget by the EmbedPress Plugin on an Elementor page to display a locally hosted PDF. I want to be able to see the PDF URL in the advanced editor in WPML so that I can translate the PDF URL. I used a code snippet in Custom XML Configuration to achieve the same result for an Elementor button, and it worked. I added another snippet to achieve the same with the EmbedPress PDF widget, but it is not showing.
Symptoms:
The PDF URL is not showing in the advanced editor in WPML for translation.
Questions:
How can I make the PDF URL visible in the advanced editor in WPML for translation?
