AWS Amplify and AWS CodePipelines integration

I am using AWS Amplify to build and deploy my app. It is configured to build and deploy a preview of the app for each Merge Request in GitLab. This works great on the AWS side of things but there is no status available on the Merge Request in GitLab.

I am unsure whether this is a limitation of AWS Amplify, GitLab or both. It does work well with GitHub Statuses as seen in the pr-reviews documentation.

Is there a way to integrate external build pipelines such as AWS Amplify or AWS CodePipelines with GitLab Pipelines?
