2X Parallels Client App - Too Many Shortcuts!
As far as I can tell, you only have the possibility to block an app from creating a shortcut on install.
I believe that it's against Googles Playstore rules to spam the user with such shortcuts. You can try to contact the developer and if they don't react you can contact Google.
