如何在Jenkins声明性管道中发送“返回正常”通知？

pipeline {
    agent any
    stages {
        stage('Build') {
            steps {
                // 执行构建步骤
            }
        }
        stage('Test') {
            steps {
                // 执行测试步骤
            }
        }
        stage('Notify') {
            steps {
                emailext (
                    to: 'recipient@example.com',
                    from: 'jenkins@example.com',
                    subject: 'Build Status',
                    body: 'Build completed successfully.'
                )
            }
        }
    }
}
