They don’t have the ella theme in the Shopify store so I will have to ask some follow up questions to get a better idea.
- First, are these your icons? If not, are you okay with using other icons that are very similar?
- Do you have a URL we can take a look at your product page? This will make it easier giving you the steps.
- When you go into the customizer and head over to your product page; when you hover below your description does it give you a little + icon to add an additional section or custom liquid code?
