Is it possible to show games on the PS4 only in one account?

I have the problem that I have several accounts on my PS4 and like certain games like gta5 would only show on certain accounts. I bought Gta5 in the playstation store. Unfortunately, I have the game available on all acc, but my children are not allowed to play it. So, can I just show the game for -one- certain acc? That means in the menu bar where all applications can be found?

No, but you can set age limits for the other accounts - if they're family accounts

Yes, but the problem is that my sons are 13 and 14 and they know what GTA5 is and they should not notice that I have the SPiel at all so they do not play it themselves! +

But nothing is.

Thank you.
