I made an account for my wife where she has non administrator privileges.
Among the music programs which she needs is Rosegarden.
There are 2 problems:

1. None of the programs I install for her appear in her Activities screen.
   She can search for them, but I assume she won't remember what the names are for searching.
   Here is what the search shows:
   

   
   



2. Rosegarden cannot be made a favorite

   
   

What can I do to help her? If I log in user her user name, I have no sudo commands.
I can still access her files from my account where sudo exists.
Clearly I won't be able to change applications in her activities screen from my account.

Edit: to correct the desktop file, I added the line (but it didn't help):

StartupWMClass="Rosegarden"

Looking glass gave me

Untitled - Rosegarden

wmclass Rosegarden

<untracked>

Edit2: I still don't understand what exactly causes an application to become visible in Activities without it being searched for. I thought perhaps there is a program which might scan on startup, so I put rosegarden on the desktop and pinned Qsynth and Qjack to the favorites bar.

Then I logged off, and even tried to power down, but they still remain invisible in Activities (without doing a search). So that remains a mystery, but at least my wife has enough to work without being forced to remember program names. Perhaps in time the programs will become magically visible???

Likewise I can forward a link to this discussion to the rosegarden developers so they have a good idea what needs to be fixed. What I did fix is a good start but not sufficient.

Thanks in advance for all advice.
