For now, all notifications are sent from one channel, they have the same icon. I recommend that each notification type should own a channel and icon. Once each notification type owns a channel, we can choose which notifications pop up or not. Also, the icons help recognize notification types. The types of notifications are as follows: Invites (includes replies) Invite Requests (includes replies) Friend Requests Groups (e.g. Join Request, an announcement from groups) Other (e.g. promotion of trust ranks, Impostor generation) In addition, the notifications and channels in the attached image were generated by the application I created. there is no exist in the original app. Read more about notification channels: https://developer.android.com/develop/ui/views/notifications/channels
