Is there any setting in Confluence to get email notification if anyone choose me as a content approver? I do not get such email notifications now....
This function is not built into Confluence. There are a couple of addons on the marketplace (e.g. Document Control for Confluence Cloud ) which offer this functionality.
We built this addon for this usecase, and there are also some other addons with their pros and cons available.
I think you can set this up with the Confluence app for Slack.
