How to use the @aws-cdk/aws-codepipeline-actions.EcrSourceAction function in @aws-cdk/aws-codepipeline-actions

fargatesvc.targetGroup.configureHealthCheck({
            interval: Duration.seconds(5),
            healthyHttpCodes: '200',
            healthyThresholdCount: 2,
            unhealthyThresholdCount: 3,
            timeout: Duration.seconds(4),
        })

        const sourceActionECR = new codepipeline_actions.EcrSourceAction({
