Ghaziabad Nagar Nigam — Unavailability of Ghaziabad Nagar Nigam Pet registration app

As been initimated by our veterinarian yesterday, we want to register our pets under the Ghaziabad Nagar Nigam.
As per the various sources of news, which states that there is an app for the registration of pet online, we are unable to find such an app under Google Play Store. Hence the need to rectify the availability of the app or provision of alternative link for registration.
