Using find & replace on a string with a regex pattern
@([A-Za-z0-9_]+) allows you to find a @mention in a sentence.
It would be awesome to add the ability to extract a word within a string
:extract only allows the user to extract an email. If you added the ability to extract text from a string, with a regex pattern then it would be possible to trigger a workflow when a username is mentioned, (although mentions themselves wouldn’t be clickable).
