Continuity pop-up is not helpful

Upgraded to a new Macbook. Now I'm occasionally getting helpful Mac feature popups that are not always very helpful. Such as todays an the subject of Continuity. Specifically, slide #2, "Hand off to your Mac".

It says:

When you start something on one device, you can pick it up on your Mac. The icon of the app you’re using appears at the end of the Dock — click it to keep working.

I do not see anything at the end of my dock when using any app, except what is always there: My App shortcuts that are always to the left of the divider, and 'Downloads' and 'Trash' that are always to the right of divider.

Maybe these pop-up feature things would be a little more useful if they contained a link to some more detailed documentation than a couple of ambiguous sentences.
