Build Periodically Syntax for Jenkins Configuration as Code Plug-In (JCasC)

I'm trying to use the configuration as code (JCasC) plug-in to create a pipeline job that builds periodically, but I can't find the syntax for this anywhere online. I'm writing the configuration in YAML.

The "Build Periodically" field is under Build Triggers in the pipeline jobs and has a text field called Schedule. My schedule is 0 6-19 * * *

Is this even possible to do?

This is the yaml file that I am trying to edit:

jobs:
  - script: >
      folder('test1'){
        pipelineJob('test1/seedJobTest') {
          description 'seedJobTest'
          logRotator {
            daysToKeep 10
          }
          definition {
            cpsScm {
              scm {
                git {
                  remote {
                    credentials "xxx"
                    url 'xxx'
                  }
                  branches 'refs/head/master'
                  scriptPath 'Jenkinsfile'
                  extensions { }
                }
              }
            }
          }
          configure { project ->
            project / 'properties' / 'EnvInjectJobProperty' {
              'on'('true')
              'info' {
                'propertiesContent'('BRANCH=master')
              }
            }
            project / 'properties' / 'org.jenkinsci.plugins.workflow.job.properties.DisableConcurrentBuildsJobProperty' {}
          }
        }
      }

If using JCasC to configure your build/pipeline configuration:

To build periodically, regardless of SCM changes, you can add this block:

triggers { 
    cron('0 6-19 * * *')
}

To build periodically, only if there were SCM changes, you can use this block:

triggers {
    scm('0 6-19 * * *')
}

To view this answer in context, here is a code snippet example:

jobs:
  - script: |
    job('PROJ-unit-tests') {
        scm {
            git(gitUrl)
        }
        triggers { 
            cron('0 6-19 * * *')
        }
        steps {
            maven('-e clean test')
        }
    }
