We've developed a bot and are sending rich cards to the client. When a user connects to our bot through web chat and clicks a button within those rich cards, the text of the buttons the user clicked on are not echoed to the chat window as if the user would have typed it himself, unlike messenger for example.
The problem with this is that if the user scrolls up in the conversation, all he sees is text written by the bot and it makes it hard for him to see what choices he's made (what buttons were clicked), and therefore what bot's answers correspond to what choice.
