Is it possible to change the title of this question to make it clear from the question that this about how to skip notifications for ones own actions? e.g. "Confluence <> Slack integration - skip notifications for my own actions?" It took me a while to find this.
I have this same problem, too, and it is driving me crazy. It significantly limits the usefulness of these notifications for me. I make a lot of changes. I do NOT need notifications of my own changes! Not only do I not need them but it makes it very difficult for me to notice and find the notifications when *others* make changes.
