### Proposal
You can currently set that you want to be notified when a tag is added or removed via Slack Message.

It would be desirable to be able to set for which tags you would like to receive a message. The simplest division would be e.g. only protected tags. However, it would be better to have more precise control, e.g. via a regex, for which tags you would like to receive a notification or not.
<!--Use this section to explain the feature and how it will work. It can be helpful to add technical details, design proposals, and links to related epics or issues.-->
<!--Consider adding related issues and epics to this issue. You can also reference the Feature Proposal Template (https://gitlab.com/gitlab-org/gitlab/-/blob/master/.gitlab/issue_templates/Feature%20proposal%20-%20detailed.md) for additional details to consider adding to this issue. Additionally, as a data oriented organization, when your feature exits planning breakdown, consider adding the `What does success look like, and how can we measure that?` section.-->
