how to tell JHipster JDL to enable 'API first development'?

Question

When I generate a JHipster application manually, I get asked whether I want to to go with a 'API first'-approach (e.g.: Which other technologies would you like to use? > API first development using OpenAPI-generator)

How can I do the same if want to create the application with a JDL-file? e.g.:

application {
  config {
    baseName myapp
    applicationType monolith
    devDatabaseType mysql
    prodDatabaseType mysql
    buildTool maven
    clientFramework react
    enableTranslation true
    nativeLanguage en
    languages [en, de]
    enableOpenApi true <-- What is the correct way to enable OpenAPI?
  }
  entities *
}

jhipster export-jdl export.jh
cat export.jh
