Hi @skinny85 and @LuqiPan
I would like to contribute this implementation for this issue and I have the same problem too, but I used L1 CDK construct to resolve my problem.

This issue also need to Implement chatbot.CfnSlackChannelConfiguration and codestarnotifications.CfnNotificationRule.

The use case and pseudo code like as below:

const codebuildProject = new codebuild.Project(this, 'MyCodebuild', {...});

const slackChannel = new chatbot.SlackChannelConfiguration(this, 'MySlackChannel', {...});
const topic = new sns.Topic(this, 'MyTopic', {...});

codebuildProject.addNotification({
  notificationRuleName: 'MyNotificationRule',
  targets: [
    new SlackNotificationTarget(slackChannel),
    new SNSTopicNotificationTarget(topic),
  ],
  events: [
    ProjectEvent.BUILD_STATE_SUCCEEDED,
    ProjectEvent.BUILD_STATE_FAILED,
  ],
});

Maybe you can see that in few days. :)
