Tell me how to configure my Google Domains for international Shopify shops

I have a Shopify store in the US and am going to open a store in Europe. I want to make sure my subdomain forwarding is set up right in Google Domains. Here is what I'd like to do:

–My main domain in the US is [login to view URL]

–For my European store (which is a separate Shopify shop), I want to set up a subdomain [login to view URL]

–In Shopify, I can use an app to redirect customers to the relevant site, based on their location

–I want visitors to feel like the US Shopify shop and the EU Shopify shops are the same but targeting different regions

Here's what I want you to do: tell me how to configure my Google Domains to make this work (see screenshot).
