Hello, I am using Jira Cloud, mix of Jira Software and Jira Service Management.
I am trying to do the following:
I have ProjectA (either JS or JSM) and ProjectB (either JS or JSM),also the respective usersA and usersB.
I would like for usersB to be able to view and/or get a filter, board, report that contains certain information from projectA without them being able to view the project itself. Example: I am from usersA and want to user JQL filter that searches for specific issues in projectB but I shouldn't be able to view any data from projectB.
I have tried with View Aggregated Data but I can't seem to make it work 
Any help would be appreciated, Thanks
