HD 8 5thGen share Google Play apps on child profile?

[dooie07]

I have purchased my daughter a Fire HD 8 5th Gen. I have successfully installed Google play store and added a number of apps.. so far so good.
I'm now wanting to share these on her profile, but none of the Google apps are listed as shareable when i look to add apps.... any ideas or is this not possible?

On some tablets you have to register a gmail on the other profile so you can download apps from the Play Store.
I'm not familiar with the Fire tablets but it could be something similar.
