URL on the message doesn’t work if the message is sent by the Flow action
With using the Send me an email notification option via the Flow action, URL on the message doesn’t work and line breaks on the message won’t be reflected if the message is sent to Teams channel. I would request you to fix the behavior.

I have a similar issue with the "Post a message (V3)" Flow action when it posts a tweet to our Teams channel. Any URL embedded in the tweet text (or whatever text) should be converted to a clickable hyperlink when posting it to a Teams channel.
