[Blind-sysadmins] Microsoft Teams reading messages from webhook

Hi guys, Trying to re-write some chat bots to work with Teams instead of Slack. I am using the simple incoming webhook with a standard json text payload. I can't seem to read the messages using the arrow keys with JFW. If I use arrow keys and press enter it does go into the message in order for me to reply, but it won't read the contents. I have managed to get JFW to announce that I am interacting with a card message, but never read the message out. Anyone else seen this? Thanks. Andrew.
