Google Assistant app has been uploaded to play store by Google and is now available to download. But it is just a shortcut which allows launching assistant app if it already available on your smartphone.

With this app, you can launch Google Assistant with a single tap on the assistant app icon installed from play store and no need to touch and hold the home button.

By having a separate app on play store, Google can able to provide frequent updates and other improvements to the assistant app. Hope for more improvements in future.
