How to add the dynamic Shop Pay button on ecomposer builder

[CPR]

Hi Community!

I am building a separate page for a product on ecomposer builder app. However, I want to add in the shop pay button like the rest of my theme product pages have. The only option ecomposer builder has is to insert an image which I have done but it doesn't click through to a dynamic checkout. 

Do I have to insert some code somewhere? and what should the code be. 

My theme product product page is https://www.smithandsinclair.com/collections/boozy-brunch-jam/products/boozy-brunch-jam?variant=4046...

as you will see in the first picture. 

The page I want to add in the dynamic shop pay button (which only has the image no click-through) is the

 second image below

I'm so lost 😕 any help or guidance would be appreciated

Thank you

Chloe

Thank you for your speedy response @Ademola-Smart . 

I have followed the steps and it comes out as a greyed out block as seen in the photo below - it also looks like there will be two buttons and I only want SHop Pay buttons
