Hello,
The mentioned demo uses Elementor, but you are using WPBakery, so there is no option to just copy/paste content.
We’ve created a new static block on your site “Ask An Expert”, you can edit it depending on your needs and set on single product page. Here are settings from the demo – https://prnt.sc/T0YArN-za5d9 https://prnt.sc/_t9Gq6iAjjEy https://prnt.sc/0oRv3O0cBVKK https://prnt.sc/LQoHOOiU4Orh
