Hi Ravin,
As I said, this forum is specifically for questions about Corvid.
If you are not adding code to your site we are unable to assist you here.
As far as I know it is not possible to edit that confirmation email from Wix Stores but you could create your own notifications by adding code to your site.
You could use the notify() function to send yourself notifications and you decide what information is provided in those notifications. You could add the onNewOrder() function to the backend and run the notify() function upon a new order creation.
Hope this helps!
