Run multiple Jobs in parallel via Jenkins Declarative pipeline syntax-CodePudding

I want to execute multiple jobs from a single pipeline using declarative syntax in parallel. Can this be possible!! I know we can make a declarative parallel pipeline using "parallel" parameter.

pipeline {

    agent any
    parallel{
    stages {
        stage('Test1') {
            steps {
                sh 'pip install -r requirements.txt'
            }
        }
        
        stage('Test2') {
            steps {
                echo 'Stage 2'
                sh 'behave -f allure_behave.formatter:AllureFormatter -o allure-results features/scenarios/**/*.feature'
            }
        }
        
        stage('Test3') {
           steps {
                script {
                    allure([
                        includeProperties: false,
                        jdk: '',
                        properties: [],
                        reportBuildPolicy: 'ALWAYS',
                        results: [[path: 'allure-results']]
                    ])
                }
            }
        }
    }
    }
}

Below image will show you the proper flow that I want. Any approach how to do it?
