9. Known issues and limitations
 The Microsoft Teams "When a new channel message is added" trigger only fires when root
messages are added in the channel. Replies to an existing channel message will not result in
the trigger event firing.
 The message size limit for the "Post a message" action is approximately 28KB. This encompasses
all HTML elements like text, images, links, tables, mentions and so on. If the message exceeds
28KB the action will fail with an error stating: "Request Entity too large"
