Cannot access any AR functions – Filmr - Pro Video Editor Review

So far, we have a really cool advertisement in the App Store, but when we try to use the app, it looks like any basic video editing software. Not intuitive but not impossible to figure out either - except AR. How do we add the AR creatures and dancing elves and Santa and all of that? No help button. Is there a manual? I’m not against reading how to use it if someone can direct me to the manual. Searched it up on YouTube and found almost nothing. Feels like clickbait right now.
