Wordpress + elementor - adding contrast and text size changes

I have never had contact with WP and Elementator. I have a little problem, I would like to do something like this: https://ibb.co/Z6ccwT9

3 icons:

1 - Zoom in and out of text

2 - changing the contrast on the page

3 - is irrelevant for now.

How to do it in WP/Elementator? 😉 In pure HTML/jQuery this is quite simple to write... but in the WP world? 😀

I found a lot of plugins that do what I want, but generally they add their icons in various places on the website - and they cannot be attached to my icons....

Could I ask for help on this topic? 😀

Please help me
