Need to remove "home" nav from Shopify store because my homepage is in Wordpress

[GoodFoodFighter]

Hi Friendly Shopify Readers!

I am new to this forum and very grateful for the active discussions!

I just linked my Wordpress site to Shopify. When a customer clicks the buy button from my homepage (https://goodfoodfighter.com/) they go to the Shopify store here:

https://good-food-fighter.myshopify.com/products/smoothie-spree-card-game

But then they can't get back! The Shopify page has two nav items: home and catalog. But I want the home nav to go back to my website. Right now it is a blank, undesigned page.

Many thanks,

Nina, the Good Food Fighter
