None of us used Elementor or any page builder for a single product page before unfortunately.
You could try creating an Elementor template and add the shortcode using a header element?
https://docs.generatepress.com/article/header-element-overview/
But that seems to be overkill since the whole thing is already coming from Elementor.
I would still check with their support to see if they have any advice on this – sometimes you might get lucky with the support person that answers your question 🙂
