I need to write a short Java-Script code

Hello! I would like to add a special JS functionality to this page: [login to view URL] . As you can see there are "i" buttons on the screenshot which are scrolling to the appropriate section below. The section below works like an accordion, when you click on the title, it opens a new content. I would need you to write me a JS code which will make the following: the user clicks on the "i" button, is automatically scrolled to the appropriate section (this already works) and the content of that one section appears. I will apply the code to the site myself so all you need to do is to look at the source code of the website using, for example, Chrome developer tools and write me the proper JS code. I would need this as fast as possible. I am looking forward to co-operating with you! Zuzana
