Helix apps - New to helix

[needhelpplease]

Hi,

I recently changed to Helix tv. I was wondering if it's possible to add more apps onto Helix or do i only have access to the custom apps (Netflix, Stingray, Illico, ect.) that comes with Helix?

Furthermore, I used to be able to see the Lotto Quebec results on the older system. Is there a way to review these lotterie results on Helix as well?

Thank you in advance!
