Preview selected route in WhatsApp, Telegram, etc. instead of static map image

[emer7]

Current Behaviour

Currently when sharing a busrouter.sg link (e.g. https://busrouter.sg/#/services/168~858~969) in WhatsApp and Telegram, a link preview will be generated, displaying a static image of busrouter.sg map

Telegram

WhatsApp

Intended Behaviour

It would be good if preview of the selected route can be generated instead

Maybe can be implemented by dynamically changing tag for each selected route link
