Default notification tone on some apps

[Android Central Question]

Since getting Google Pixel 3XL I have found some apps only play the default tone when I receive a notification.
Is there any way to have the apps play its own tone, e.g. Snapchat play the Snapchat tone instead of default Google.

I have gone into notification settings but it hasn't been helpful.

Welcome to Android Central! Is there a separate notification option in Snapchat's own settings menu? (Sorry, I don't use Snapchat, so I can't check it myself.)

Snapchat lets you pick the sounds, but the selection is done via the new Android settings app:
phone Settings > general > apps > notifications > apps > snapchat
