Where can I submit a feature request for Wix stores

Question:
As per the title. Every article suggests there is a request feature button on the top right of the page showing other feature requests, but there isn’t. I can’t see where to add a new one.

Product:
Wix Stores (not using studio)

What are you trying to achieve:
I want the ability to add custom fulfillment/tracking URLs.
The existing list consists of big players, FedEx, DHL etc but nothing relevant for my country Australia. I can add a new provider, but only the name can be configured, not the url.
It would be so simple to allow people to create a templated url for any provider of their choice.

E.g I can enter for Australia Post a tracking url that substitutes a variable such as [tracking number] for the value entered in the tracking number field.

Track your parcels - Australia Post[tracking number]
