If you have a device running postmarketOS or Alpine Linux you can try this out yourself with other Android apps. Just "sudo apk add android-translation-layer" and then run

$ android-translation-layer some-app.apk

I tried a few (F-Droid, Spotify, Megalodon) but they all failed with various issues, looks like there's a lot of API surface still not covered. Hopefully a lot of it is fairly easy to add now that the foundational work has been done!
