Is it possible to create a round border around an Icon?

Hi,

I am using Elementor, the free version, to build my website.

I have made a small step-by-step explainer banner on my homepage using the elementor icons to give a brief explanation of how my site works.

please see:

The icons are green and the background is a lighter shade of green

I was just wondering if it was possible to create a round border around the icons and have the background, inside the border, clear to look like these icons from another website?:

Many thanks,
