(pipelines): Adding a ManualApprovalStep to a Wave

It seems that the following code does not really add the ManualApprovalStep before the build action. What would be the proper way to do this with the new CDK Pipelines?

  pipeline.addWave('CustomWave', {
    pre: [new pipelines.ManualApprovalStep('ManualApproval')],
    post: [
      new pipelines.CodeBuildStep('CustomWaveAction', {
      projectName: 'CustomWaveActionBuild',
      commands: [
          // add rest of the commands here..
      ],
    })],
  });

Environment

• CDK CLI Version : 2.0.0-rc.17 (build fb5dc58)
• Framework Version: 2.0.0-rc.17 (build fb5dc58)
• Node.js Version: 14
• OS : macOS
• Language (Version): all
