Kiosk Mode Apps / Assigned Access Apps Automatic Updates via Microsoft Store

Question

I have an app I am working on that is intended to be a kiosk mode or assigned access mode app. My current assumption is that it will auto-update with the Microsoft Store app like other Store apps. So far, that hasn't been true and the app doesn't get a new version unless I disable assigned access, sign into the user account on the PC normally and update via the Store. After that, I sign out, reconfigure assigned access, sign into the assigned access account and the app is now up-to-date.

I was assuming that maybe, I need to be a bit more forceful in checking/updating the app in my code, but I hit a wall with that, too: https://learn.microsoft.com/en-us/answers/questions/59707/how-can-we-check-the-new-version-of-app-update-is.html
