            const card2 = CardFactory.adaptiveCard(returnCard);
            card2.id = replyToID;
            const newActivity = MessageFactory.attachment(card2);
            newActivity.id = replyToID;
            newActivity.type = "message";
            await context.updateActivity(newActivity);
        }
}


// await context.sendActivity({
//     text: 'Here is a return card',
//     attachments: [CardFactory.adaptiveCard(returnCard)]
// });
//const newActivity = MessageFactory.attachment(CardFactory.adaptiveCard(returnCard));
module.exports.AdaptiveCardsBot = AdaptiveCardsBot;

Any help would be greatly appreciated.

@Pawan Please go through Updating Bot Messages . Here is a sample code in Node to update an already existing card with a new card on button click.
