I have found the shopify instructions as I have pasted below but on my settings- notifications screen, there is no "Staff order notifications" section that I can find. I am the store owner. I am on the basic plan - is this why I cannot set up notifications?
From your Shopify admin, go toSettings>Notifications.
In theStaff order notificationssection, clickAdd recipient.
From the first drop-down menu, select the email address for the notification from the following options:
SelectEmail address, and then enter a new email address that you want to send the order notification to.
Select a staff member to send notifications to their account email
