How to differentiate build triggers in Jenkins Pipeline

Question

I\'m hoping to add a conditional stage to my Jenkinsfile that runs depending on how the build was triggered. Currently we are set up such that builds are either triggered by

There was a similar requirement, where user detail who triggered the build should be there in success / failure notification. The job was already had time based triggered, hence could not use wrap([$class: 'BuildUser']) directly.

I used below step, which print username if the job is triggered manually or timer triggered. So, I used this:

pipeline {
    agent any
    stages {
        stage('Test') {
            steps {
                script{ 
                    env.buildCauses = currentBuild.rawBuild.getCauses()
                    if (buildCauses.contains("hudson.triggers.TimerTrigger")){
                        env.builduser = "TimerTrigger"
                    } else {
                        wrap([$class: 'BuildUser']) {
                            env.builduser = "${BUILD_USER}"
                        }
                    }
                }
                echo "Initiated by: ${env.builduser}"
            }
        }
    }   
}
