Sticky “on this page” navigation section in Elementor

Hi Everyone,

I was wondering if anyone can kindly suggest the best way to build, using Elementor, the “on this page section” navigation box as per the following webpage: https://www.drinkaware.co.uk/facts/health-effects-of-alcohol/effects-on-the-body/alcohol-and-sleep#drinkingcanequaladisturbednightssleep.

This has several elements to it:
1) It is a sticky sidebar, which sits below the hero, which scrolls down the page automatically.
2) It has buttons with links to sections on that specific page (ie) does a new menu need to be created for this?)
3) The buttons are highlighted as you scroll down the page, indicating where you are on the page.
4) If the “Share” button is clicked, another section below it drops down with social media icons.
5) It has a “Back to Top” button.

Is this possible with Elementor, if so, what would the cleanest way to do this? Any advice or resources would be much appreciated.

Thank you very much for your time and help.

Igor
