I am facing some problems with creating a simple "notification icon/counter" on the front page of the app when a user receives a new message in their in-app chat. It should be something like the top left corner (either a dot or a counter badge). I have used the prebuild chat, so figured I could sort for "when not in "last_message_seen_by", but can't get it to work. It would have been easy if I could filter for "when array does not contain user id", however, don't have the skills to write that as code.
Anyone who has solved this or have any suggestions?
