GitLab Mattermost - Activating Integration and Teams for Already Made Projects




I already have a GitLab CE instance self-hosted and recently I’m enabling the Mattermost integration to help us replace our Slack solution.

However, I have a question. I have a group already made within GitLab. I want to build the group within Mattermost as well with the initial population. How can I get them to sync up with users and such?

I’ve already looked through the Mattermost documentation, the GitLab’s Mattermost integration documentation, and Google Searches. However, I can’t seem to find this specific scenario out and I’m not too knowledgeable enough to solve this manually. Anyone have any suggestions on how I should proceed?
