I like the GitHub Mac app, which I use with my GitHub account. I have joined a GitLab project and I was wondering whether I can use the GitHub app with a GitLab repository. I found a post that discuss that the Windows GitHub app works with GitLab and one that show how to add a repo. Both these posts gave me hope that the GitHub Mac App would work with GitLab. I also see that you can use BitBucket with the GitHub Mac app, but I don't understand whether and how to link a GitLab repository to my GitHub Mac app.
Many thanks!
