How can I create a self update codepipeline?

Question

I am using codepipeline as CI/CD pipeline by using CDK.

I'd like to make the pipeline update by itself so I tried to create one stage in the pipeline to update the pipeline itself by running cdk deploy command.

In order to make the self update work, I need to specify a parameter selfMutation in codepipeline construct: https://docs.aws.amazon.com/cdk/api/v2/docs/aws-cdk-lib.pipelines.CodePipeline.html#selfmutation

but this property only exists in cdk v2 not v1 ( I am using cdk 1.84.0 ). What is the equivalent property in v1?
