CodePipeline does not return ARN

[meap]

I want to connect CodeStar notification rule to Pipeline, where ARN is needed as a resource value, but the pipeline does not return ARN.

I have to do manually by concatenating string which is not good.

  PipelineNotificationRule:
    Type: AWS::CodeStarNotifications::NotificationRule
    Properties:
      DetailType: FULL
      Name: !Sub '${AWS::StackName}-notification-rule'
      Resource: !Sub "arn:aws:codepipeline:${AWS::Region}:${AWS::AccountId}:${AWS::StackName}-pipeline"
      Status: ENABLED

Is there a better way? I guess the pipeline should return ARN in return values.
