Hello, the name of our Shopify public APP is ShopHub. We want to control each user account of ShopHub to only authorize shops belonging to the same Shopify account. According to the use case of our application, we chose the offline access mode when authorizing, but we were unable to obtain the email address of the Shopify account to which the Shopify shop belongs, so we could not verify whether the Shopify shop belonged to the same email address. So I want to know how to get the email of the Shopify account that a Shopify store belongs to. Is there any API that provides this function? Or are there any related setting options that can only authorize shops belonging to one account to the same ShopHub account when setting authorization?
