change text on button - app in shopify, but not native to shopify ATC button

Hello, im trying to change text on a button on my product page. its not the native ATC button. its an external app for Popcustoms print on demand customization.

Button currently says “Personalize”, but need it to say something else. and the same Popcustoms ATC button. need that changed too.

Thanks!

doesn’t sound easy. it’s either text or a button. I’m not sure you will be able to imbed a button into a text field

wrong way around. change existing button text to different text.

either have them as text with a hyperlink or remove the background color of the button…???

I dont think youre understanding what i need done. All good.
