Can't Find Adobe Stock Button

I noticed in a lot of videos being able to access Adobe Stock. I have an account but for some reason  my view isn't the same.

It looks like to access templates you go to the themes/style area and when you click the "Adobe Stock" icon appears. I can't find that button anywhere. Attached  is a view of what I see vs. what I see other folks having. 

Probably an obvious thing but what am I missing?
