Right-press the apps icon and choose Pin to Taskbar.

It should appear on your taskbar.

This should take you to Chromes app launcher.

You should see the shortcut there.

Right-tap on it and see to it Open in Window is selected.

choose the apps icon to launch it.

Its icon should appear in your Windows taskbar.

Right-choose the icon in your taskbar and choose Pin to Taskbar.

This was frustrating me a fair amount this morning, so I hope it helps some people.
