GitLab group webhooks

You can use CodeBuild GitLab group webhooks to start builds on webhook events from any repository within a GitLab group. Group webhooks work with any of the existing GitLab webhook event types, and can be configured by adding a scope configuration when creating a CodeBuild webhook. You can also use group webhooks to set up self-hosted GitLab runners within CodeBuild in order to receive WORKFLOW_JOB_QUEUED events from multiple repositories within a single project.
