Transitioning from Slack Notifications to GitLab for Slack App in Self-Hosted GitLab Instance

Hello everyone!

We’re using a self-hosted GitLab instance and are currently facing a question regarding the announcement that Slack Notifications will be deprecated, and their functionalities will be transitioned to the GitLab for Slack App.

We would like to get more detailed guidance from the community or GitLab representatives regarding this transition. How will the process of deprecating Slack Notifications be implemented? Is it a discontinuation of the use of webhooks, or do we need to completely switch to the GitLab for Slack App?

We would appreciate your assistance and insights on this matter!

Thank you!
