Mechanical Systems Kinematics Design app gone

Dear all,
since the last major update to 3DExperience the "Mechanical Systems Kinematics Design" app has vanished. Does anyone know if the features included in this app have been shifted to another app or if you need different roles to access it now?
I especially need the "mechanism representation" feature, which could only be executed in said application. If you have any advice on how to get this app back or how to use said feature since the latest update without this app, please let me know.
Thank you
