Though there were few questions regarding the similar, I don't see any working solution.
I am working on a BOT for a feedback. Currently the user is able to send multiple responses by clicking on the options provided in the adaptive card. I am trying to replace the adaptive card with a plain adaptive card that just has some plain text like , "You have chosen option 3".
The following from the link provided in above comments by subbu helps in resolving the same.
var activity = MessageFactory.Attachment(card.ToAttachment());
activity.Id = turnContext.Activity.ReplyToId;
await turnContext.UpdateActivityAsync(activity, cancellationToken);
We went with just deleting the card & sending a default response once user submits as that was enough.
