After installing Genymotion plugin and restarting Android Studio you should see the Genymotion device manager icon in the toolbar:



On newer Android Studio version the toolbar may be disabled or not fully shown. Make sure the toolbar is activated:  Menu View -> Appearance -> Toolbar



Additionally when you click the Genymotion icon the first time you have to manually specify the Genymotion installation directory, e.g. by default it should be this path:

C:\Program Files\Genymobile\Genymotion
