Make notifications silent on Android (F-Droid)

[Porrumentzio]

Sometimes when a notification appears while playing Lona, it cannot be seen.

A solve would be to activate the Silence Mode when Lona is running.

Hmm, what can't be seen? The notification or the game?

I've just tested this and it works okay in my phone. Regardless of that, I don't think that the app should mess with the notification modes of the phone. Actually the game is just html+javascript, there's no android-specific code in it.
