WordPress Content Editing -- 2

I'm seeking a WordPress expert to help me update the text on existing posts/pages. Prior experience with WordPress/PHP is a must as the text on that post is not easy to update It couldn't be found neither on WordPress customizer nor Elementor, so I believe it's being dynamically generated from somewhere else, What I exactly is to know how to edit that part in only 1 page and I will do the rest.

Below is the link of the website for an example page, you will find the part that I want to edit attached.
