Await the triggering of the selected event before running the next block.

* **Events.** An event you would like the workflow to await.
  * **Tab closed.** Wait until a tab has closed.
  * **Tab loaded.** Wait for the current tab or the tab that the URL matches the [match patterns](https://developer.mozilla.org/en-US/docs/Mozilla/Add-ons/WebExtensions/Match_patterns#examples) to be loaded.
