Need QR code, or 6 digits, for Evri parcel

I have created a shipping label for the Evri courier service. The label has been generated successfully using the API, but I need access to the QR code, or 6 digits, in order to print the label at an Evri parcel shop.

The url where Evri mentions the QR code/6 digits is here: https://www.evri.com/faqs/sending-a-parcel/i-dont-have-a-printer-what-can-i-do

Currently, I can't find the QR code or 6 digits using the API or through the easyship dashboard. These are also my shipping settings:

    shipping_settings: {
      units: {
        weight: 'kg',
        dimensions: 'cm',
      },
      additional_services: {
        qr_code: 'qr_code_with_label'
      },
    },

Any idea how I can get this QR code?
