I have tried using Expression Language #{oimcontext.currentUser.roles['SYSTEM ADMINISTRATORS'] != null} from web composer but it doesn't allow me to hide any specific catalog item. It rather hides all the catalog items.
Steps: created sandbox->Request for self-> Customize -> Structure -> Navigate to appInstance which needs to be hidden -> click edit in web composer -> Under Display Option Tab -> Added EL #{oimcontext.currentUser.roles['SYSTEM ADMINISTRATORS'] != null} -> apply ok.
I've also tried changing the ORG in application instance and defining IS_REQUESTABLE=0. But they didn't seem to help.
Can somebody help me out with this? Thanks in advance.
