Find what specific plugin or program used by two sites

I found that two diferent sites (one in wordpress and the other in shopify) are using the same extension to make possible fot the clientes to insert their personal sports data and image (croped and removed background). Fot this project I just want to know the name of that specifi program or extension that produces those results. I will be using woocomerce in my site and I want to replicate that.

The sites with those features are:
https://myfutcard.com/en/build-your-card/?product_id=1003901&variation_id=1003902
and
https://pt.cardsplug.com/products/fc25-team-of-the-year?view=fb-customize&variant=44172772704432

Thanks
