try {
                          echo "Checkout ITs from branch: ${ITS_BRANCH}"
                          checkout([$class: 'GitSCM',
                                  branches: [[name: ITS_BRANCH]],
                                  extensions: [[$class: 'CloneOption', depth: 1, noTags: true, shallow: true]],

And then another background task generated at the *path operation function* will write a message using the `email` path parameter.

## Technical Details

The class `BackgroundTasks` comes directly from <a href="https://www.starlette.io/background/" class="external-link" target="_blank">`starlette.background`</a>.
