Trigger rule when task description or comment is changed/edited

I’ve been thinking for a while that there should be a rule like, “When the description is revised or added, contact the relevant parties.”

I recently saw a related post.

I also saw another post that said, “When a comment is added.”

This seems difficult because the rule trigger does not have any options related to the task description.


In fact, in the case of comments, there is a trigger for adding a comment, but there is no trigger for changing the comment.
