Tooltip doesn't show on hover?

It seems ironic that the tooltips on the docs page (like for the Copy Code icon) work the way tooltips are expected to work on a desktop browser (i.e. display on hover) but the Tooltip component that the docs describe doesn't seem to offer that functionality :)

Currently I'm not sure how this component is different from a button?

I can appreciate that on click is useful and necessary for mobile devices but it's not useful for desktop, where the idea is that a tooltip provides information about the element you are hovering over.

Am I doing it wrong? Is there a way to get it to show the text on hover?

The one on the IBM live demo works as expected: https://carbondesignsystem.com/components/tooltip/usage/#live-demo
