Describe alternatives you've considered
Combine the notification which is same channel that like slack, or kakaotalk.

Additional context
I can't find notification trigger part on chat. I want to know where is the code that triggers notification.

I've posted related issue in Expo earlier!! You might want to see here expo/expo#11042.

I think still it is not possible using expo-notification :(

How about first one? That "Delete same channel notification if enter the chat channel." one does not need collapse notification function. I'll try make disscussion for collapse notification on expo, but They don't seem to want to apply that function.

The first approach looks great~!
