Typing: In a .chat transcript, you can simulate the bot’s typing indicator with the Typing activity, optionally followed by a [Delay=...] . This matches the intent to pause before sending the next message.
AttachmentLayout=carousel: When sending multiple attachments (the two watch images), set the layout to carousel so the Emulator displays the attachments horizontally as a card carousel.
Adaptive Card attachment: The JSON file cards\watchProfileCard.json represents an Adaptive Card; specify adaptivecard so the Emulator renders the card.
Resulting .chat snippet (essentials):
