I've always wondered if the application must call createNotificationChannel on every startup or to have they created once on first use is guaranteed to be fine...
I ask that because many tutorials like this: https://stackoverflow.com/a/5394210/5679560 suggest to do that during Application onCreate which means every start of the app
But, unless there is a way for the user or other app, manually delete the channel, I could simple create these channels on first app run
what is the correct approach
