There is no way to record incoming or outgoing calls on Xperia XA2. This due to the fact that there may be a legal provision in certain countries restraining you from recording telephone conversation at all, or without any warning to the other party. Hence, call recording apps are blocked and will not work on devices running on Android 9.0.
I hope that answered your question!
