I have created a custom app for shopify seller. I am using order graphql api to create draft order, complete draft order, cancel order and return order.
so i am able to create a return in shopify with help of graphql api.
I use following ocde in python to create a return. it is successfully creating returns.

query = '''
mutation returnCreateMutation {
  returnCreate(
    returnInput: {
      orderId: "%s",
      returnLineItems: [
        {
          fulfillmentLineItemId: "%s",
          quantity: %s,
          returnReason: OTHER
          returnReasonNote: "%s"
        }
     ],
     notifyCustomer: false
   }
  )
  {
    return {
      id
    }
    userErrors {
      field
      message
    }
  }
}
''' % (order_id, item_id, quantity, reason)

now i want return shipping label for this return created. how do i get that ?
for example if shopify seller has update tracking id and url for this return then how do I get,
also i was not able to add tracking url and tracking id for returned in shopify admin for all order that i returned with api.
can someone pls help with this ?
