Changing notification sound for different apps

Hello team,

Can you please be so kind to answer my question: Is it possible on BV9500 plus (Android 9) to change default notification sound for different apps? For example: one sound for Viber, other for Gmail, third for What's up etc. For this model I found only default notification sound (in Sounds). I'm not used to have same sound (for example Viber sound) for all app notifications.
