Currently Sharing rule(Data permissions) are not applicable in JO program to restrict the data(read/write) from other users (Non admins).
Super admin has created a MDA object and added a Sharing rule(Data permissions) to restrict the data(read/write) from other users.
If non admin logins , They won’t be having access to the object.
But they have the access to make use of that object in JO fetch (source) to pull the data and run the program.
Customer want to restrict the object to be shown in the source fetch as well.
