If I use the old "Post to Teams Channel" action, I can wrap a url in the <a href="http://blahblah">Click here</a> html code, but I cannot @ a user using the new <at>username@emailaddress.com</at>
So I am using the posting as a flow bot. It does the @ correctly, but the HTML is ignored and it just posts the URL as an unclickable length of text. Even if I am using dynamic data from a Power BI connector, which provides a Tile URL, even that gets expanded into 3-4 lines of text.
Any ideas?
