How do I install Google Play Store in Genymotion using Open GApps?

Click the Open GApps button in the right-side toolbar, accept the disclaimer, and let the package download and flash. Reboot the virtual device when prompted, then open Google Play from the Android app drawer.

Google Play Store is not preinstalled, and Genymotion says to use its built-in Open GApps feature rather than manually installing packages from opengapps.org. See Install Applications and I can't find Google Play Store. Where is it? for the exact steps.
