[Elite Dangerous] Commander edition benefits only for the primary account?

o7

Today me and my girlfriend finally bought the game on ps4. We only have one console, so game was purchased on my account (primary), and she also plays on her account (secondary)

We have noticed that she does not have the Horizons add-on, while I do.

I this the way it is or do I have to do something to activate Horizons add-on for her!

Thanks for any help!
