ShellScriptAction equivalent in CDKV2

I have a project in CDKv1 which i am upgrading to CDKv2. I have a Gitleaks stage in my AWS CodePipeline using CDKv1. Now i want to move this functionality to CDKv2 but the ShellScriptAction is deprecated. I tried out with ShellStep but ShellStep does not have the project property - LINK.

export class GitleaksReviewAction extends Construct {
  public readonly action: ShellScriptAction;
  public readonly gitleaksImage: DockerImageAsset;

  constructor(scope: Construct, id: string, props: GitleaksReviewActionProps) {
    super(scope, id);
    this.gitleaksImage = new DockerImageAsset(this, "gitleaksDockerAsset", {
      directory: path.join(__dirname, "../assets/gitleaks"),
    });
    this.action = new ShellScriptAction({
      actionName: "Gitleaks",
      additionalArtifacts: [props.sourceArtifact],
      commands: [
        "find . -type d -exec chmod 777 {} \\;",
        "find . -type f -exec chmod 666 {} \\;",
        `aws ecr get-login-password --region $AWS_REGION | docker login -u AWS --password-stdin ${this.gitleaksImage.imageUri}`,
        `docker run -v $(pwd):/repo ${this.gitleaksImage.imageUri} --path=/repo --repo-config-path=config/gitleaks/gitleaks.toml --verbose`,
      ],
      environment: {
        buildImage: codebuild.LinuxBuildImage.STANDARD_5_0,
        privileged: true,
      },
    });
  }
}

Used to call the class with this -

gitleaksReviewAction.gitleaksImage.repository.grantPull(
      gitleaksReviewAction.action.project
    );

Is there an equivalent in the CDKv2 which returns the project property?

Pipeline code -

export class Pipeline extends cdk.Stack {
  constructor(scope: Construct, id: string, props?: cdk.StackProps) {
    super(scope, id, props);

    ...

    const pipeline = new CodePipeline(this, "Pipeline", {
      pipelineName: "pipeline",
      synth: new CodeBuildStep("SynthStep", {
        input: CodePipelineSource.codeCommit(repo, "mainline"),
        buildEnvironment: {
          computeType: CodeBuild.ComputeType.MEDIUM,
          buildImage: CodeBuild.LinuxBuildImage.STANDARD_5_0,
        },
        partialBuildSpec: buildSpec,
        commands: [],
        role: codeBuildSynthRole,
        primaryOutputDirectory: "cdk/cdk.out",
      }),
      crossAccountKeys: true,
      selfMutation: true,
      dockerEnabledForSelfMutation: true,
    });

    const review = new ReviewPipelineStage(this, "Review", {
      sourceFileSet: pipeline.cloudAssemblyFileSet,
    });

    const reviewStage = pipeline.addStage(review);

    const gitleaksReviewAction = new GitleaksReviewAction(
      this,
      "GitleaksReviewAction",
      {
        sourceFileSet: pipeline.cloudAssemblyFileSet,
      }
    );

    reviewStage.addPost(gitleaksReviewAction.action);
    gitleaksReviewAction.gitleaksImage.repository.grantPull(
      gitleaksReviewAction.action.project
    );
  }
}
