Customize Designer 9.6


I would like to add a new contextual menu to the Service Development Perspective, on the Designer 9.6.
I’ve created a plugin to do that, but the new contextual menu is only available on Java Perspective. I could not find it on Service Development Perspective.

Does any one know how to customize Service Development Perspective to add a new contextual ? (on right click on a package)

Thanks in advance,
