We use the organization pipeline setup where jenkins detects any repos and branches with a Jenkinsfile automatically from our Github Enterprise organizations. When a new build is being triggered through a commit, it doesnt show the normal Github icons we see in regular jobs. Hovering over the icon shows 'Branch Indexing'.
