Customer account links are not showing
By default, customer accounts are not enabled when you open a new Shopify store, which is why you may not see the links in the header. In order to show the customer accounts related links, you will need to enable this feature on your Shopify store. You can find the detailed instructions in Shopify documentation: https://help.shopify.com/en/manual/customers/customer-accounts#set-your-customer-account-preferences
