ATTENTION, this app it's only a quick shorcut to launch tv.apple.com.
Requirements: -Installation of apps from “unknown sources” allowed. -Firefox for FireOS installed (You can download the apk from apk mirror)
Steps: -Install the apk, then you can find the Apple TV+ tile in your app drawer. -Move the app to favorites if you want it. -The app use the default browser, so you can use any other web browser, but I recommend Firefox cause work acceptable for this web page.

Are you sure Firefox supports Apple TV Video Playback? I know that it used to support earlier but last time I checked again a couple of months back, it wasn't. After trying numerous browsers, I found that only TV Bro was able to play but that too fails numerous times.
