With the right mouse button you could click on the inserts button to have the list of active plugins and access them directly, at least with version 14. From 15 this possibility is no longer available, even if the pop-up (here in Italian) says that it is possible).
Steinberg responded to my support request and confirmed the problem. A bug report (CAN-64267) was created and forwarded to the developers. Support will let me know as soon as the developers have looked at the report and shared their assessment.
