Klaviyo "Notify Me" Button Looks Like Text Instead of a Button – How to Style It?

[Kaloso_Makhokolo]

Hey everyone, I’ve successfully replaced the grey Sold Out button with a Notify Me button for Back in Stock notifications using Klaviyo in Shopify. The problem is that the button doesn’t look like an actual button—it’s just black text with no background.

I want to:
Change the text to white
Add a black background

I’m using Klaviyo’s default integration with this script in my theme.liquid file:

Does anyone know the correct way to style this button so it looks right on the product page? Thanks in advance!
