CDK's CodePipeline or CodeBuildStep are leaving an S3 bucket behind, is there a way of automatically removing it?

Question

I'm creating a CloudFormation stack using CDK with code roughly like this:

export class PipelineStack extends cdk.Stack {
    constructor(scope: Construct, id: string, props: PipelineStackProps) {
        super(scope, id, props)
        new pipelines.CodePipeline(this, id, {
            pipelineName: id,
            synth: new pipelines.CodeBuildStep("Synth", {
                    input: pipelines.CodePipelineSource.connection(props.githubRepo, props.repoBranch, {connectionArn: props.repoConnectionArn}),
                    installCommands: ["npm install -g aws-cdk"],
                    commands: ["npm ci", "npx cdk synth"],
                },
            ),
        })
    }
}

and that stack creates an S3 bucket that when I delete the stack isn't deleted with it. I searched for options and I couldn't find any to control that behaviour. Is it possible to mark that S3 bucket as cdk.RemovalPolicy.DESTROY or something like that?
