Where to find log files for failed push notification?

Question

When I try to create and send a push notificartion to my Android TV, I get following toast message on my TV:

Developer warning for package *. Failed to post notification on channel "default". See logs for more details.

Where are those log files saved to?

I've found it in usual logcat. But not under app package's logs, but just in unfiltered system ones, like:

2021-12-17 01:27:54.257 665-1957/? E/NotificationService: No Channel found for pkg=com.company.appname, channelId=default, id=0, tag=null, opPkg=com.company.appname, callingUid=10131, userId=0, incomingUserId=0, notificationUid=10131, notification=Notification(channel=default pri=0 contentView=null vibrate=null sound=null defaults=0x0 flags=0x10 color=0xffffffff vis=PRIVATE)
