Custom Email Signup Pop-up for Klaviyo on Shopify

Hello, I need a custom pop-up created for my shopify store to synch to Klaviyo. I already had the popup designed and coded on shopify for mailchimp but I switched to Klaviyo this week and they told me since the form was custom coded on Shopify, it could not be redirected to Klaviyo. I hired another dev to do this but he did not have the knowledge to make the pop-up exactly as per my needs. First he did it in the Klaviyo form editor but it had too many restrictions so he could not match my design. Then he did it in shopify via an app but still he could not meet my design. I need the pop-up to look exactly as it was before for mailchimp. Please find design attached. If you can make it exactly the same, please let me know. By exactly the same I mean: 1. Size 2. Proportions 3. Font size and style 4. Font positioning within the padding 5. Logo size and positioning 6. Exit button exactly the same 7. Join button size, style and positioning exactly the same 8. Input email line style, size and positioning exactly the same 9. No powered by logo on the pop-up from any third party app 10. No hover effects when over the join or exit button. Thank you!
