How to create aab (bundle) via Fastlane?

I want to create aab (bundle) via Fastlane, but so far I was able to create only apk, here is my lane now, how to create aab?

 lane :beta do
    store_password = prompt(text: "Signing Store Password: ", secure_text: true)
    key_password = prompt(text: "Alias Key Password: ", secure_text: true)
    releaseFilePath = File.join(Dir.pwd, "..", "my-release-key.keystore")
    gradle(task: 'clean')
    gradle(
      task: 'assemble',
      build_type: 'Release',
      print_command: false,
      properties: {
        "android.injected.signing.store.file" => releaseFilePath,
        "android.injected.signing.store.password" => store_password,
        "android.injected.signing.key.alias" => "my-key-alias",
        "android.injected.signing.key.password" => key_password,
      }
    )
    upload_to_play_store(
      track: 'internal'
    )

Changing task from assemble to bundle, solved my issue!
