What is the purpose of service_discovery attribute in CarrierService POST API call?

Shopify Partner

While registering our app as a rate provider we make the following call to CarrierService API.


  "carrier_service": {
    "name": "Shipping Rate Provider",
    "callback_url": "http://shippingrateprovider.com",
    "service_discovery": true



The description of service_discovery option is as follows from docs:

Whether merchants are able to send dummy data to your service through the Shopify admin to see shipping rate examples. 

I am unable to find this in Shopify Admin on a development store. How we can send this dummy data?
