How do I make my Klaviyo pop-up Bigger on Shopify Dawn theme?

[Ecomseller2025]

Hello,

How do I make my Klaviyo pop-up Bigger on Shopify Dawn theme? It looks perfect mobile view but when viewed on desktop, it looks very tiny so how do I make sure the pop-up occupies the correct center space on the desktop view so that the customer doesn't have to zoom in to the webpage to view what is mentioned in my Klaviyo pop-up which is basically "Enter your email address for 10% off coupon" . I am using the Shopify Dawn theme version 10.0.0.0
