Subscribers List details

I am currently using the following API
GET https://apps.aistudiocraft.in/api/v1/whatsapp/subscriber/list

While this helps list subscribers, I have two important requirements:

Ability to sort the subscriber list based on the timestamp of the last message sent/received (in descending order).Ability to retrieve the unread message count for each subscriber.

These features are critical for building a dashboard and prioritising engagement.

Kindly let me know if:

There is an API already supporting this.Or if this enhancement can be added to the current API or exposed via a new endpoint.

Thank you for your feedback. We are currently evaluating this feature for future updates to enhance our WhatsApp Chatbot platform.
