To display the referral notification pop-up and allow customers to sign up for your program directly, you need to enable the ReferRush app embeds within your Shopify theme customizer.
In the App Embeds panel, you will see a list of available embeds from your installed apps. Locate the widgets provided by ReferRush, which should be named something like:
Notification Popup by ReferRush
Signup Form Widget by ReferRush
Toggle the switch next to each of these widgets to the “on” or “enabled” position.
Crucially, click the “Save” button in the top-right corner of the theme customizer to apply these changes to your live store.
With the widgets enabled, the ReferRush pop-up and sign-up form can now appear on your store. You can further customize their appearance and content within the ReferRush dashboard
