An operation representing creation of a new topic. Calling any method ([getErrors](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_topicoperation#getErrors), [getResult](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_topicoperation#getResult), or [isSuccessful](https://developers.google.com/google-ads/scripts/docs/reference/adsapp/adsapp_topicoperation#isSuccessful)) will cause the operation to execute and create the topic. To make the script more efficient, it's recommended that you store the operations in an array and only call these methods once you've constructed all the operations you want.
