How to apply an interaction to only one CMS item

Hi there, help needed.

I want to add modal when users click “Perusal” button.
The Perusal button is one of the options for the product.

I was planning to set the id of the Perusal button and click on the element of that ID to have a pop-up appear.

However, these options are in cms, so when I set the id on the Perusal button, the other options are automatically given the same id.
(webflow ecommerce product option)

I’m attaching the relevant image together, so if you know how to solve it, please help me…
