Missing the "Manage content" button in launches

I created a new launch in AEM and i see it when I go to Tools > Sites > Launches. When I select the launch I'm expecting to see the button "Manage content" (as per the tutorial and documentation) to start adding pages to the launch, but I don't have that button. I'm logged in as admin. I can access the launch pages from the source page but I want to see the launch in a view similar to site admin.
