Helix Apps - not in US App Store - Apple

I recently purchased a Helix subscription and tried to download the apps but my iPhone is in the US App Store. I can’t switch to the Canadian App Store because I currently have subscriptions that I’ve paid for from the US App Store which I will lose if I switch. Why aren’t the helix apps available in the US App Store? I know this seems like a niche problem, but I feel like I’m missing out on the whole experience without the apps, especially the TV app. Are there any work arounds?
