How to Place Launch Buttons for Installed Applications within Panel/Dock?

The Plank is nice, but I would prefer to have launch buttons for my installed software applications (like Firefox, Libre and GIMP) located instead within the (top) pane/doc.

As is shown here.

How can I do this? I am using Ubuntu Budgie 18.04 and the “add applets to panel” function under Desktop Settings only lists Budgie apps not installed software.

Thanks. But how would a casual user figure that solution out? Still hoping for an operators’ manual on Budgie … someday :slight_smile: The purpose of the Raven is another mystery, but I digress.
