Product Personalization Window

Site URL: https://www.socorrosociety.com/

I'm looking to add customizable embroidery to the fabric face masks I make, and I am looking for a way to add a window that will preview the text that they choose. This is what I would like it to look like this If you click the Personalize It button you'll see what I mean.

My question is: Does anyone know of a Squarespace plugin that will do this? This website uses Shopify, I wasn't sure if there was one for Squarespace. I'm having trouble finding plugins that aren't 3D renditions or elaborate picture ones that are really expensive. 

Commenting to see if you found a solution, as we'd like to do something similar for our business. We essentially want what Amazon does during the customization checkout process.
