plugins – How do I identify source of injected on hover?

I have an Elementor site. I know some HTML and CSS. But I don’t know how to identify (I suppose) the Elementor file that has the code that injects inline CSS code on the submenu items on hover. I know how to identify the external CSS sources, but not this one that is hardcoded on hover.

enter image description here

This is the site: you can see the code injection on the nav hover.

I have tried anything I know and asked for help on Elementor support, and they don’t answer Custom CSS-related questions.

Hope maybe someone can give me a hand on this. Appreciated.
