Better Pop Up

I am creating a one-page site https://drmarie.admaticonsulting.com/home-3/ I want to have pop-ups for more information, which I have tied to 2 links in the page.

I’m using the ‘popup builder’ plugin. I don’t like the look of it, and want something more professional.

I’ve checked others
https://www.ads-software.com/plugins/popup-click/
https://supsystic.com/
and ‘Hustle’

none seem to fit the bill, or don’t pop-up based on a click (or I don’t know how to make them).

Looking for one that looks more modern and professional, easy to use, pops up on a click, looks good on mobile and desktop.

Does anyone know of one?
