Can you leave a group chat without everybody being told?
Usually not — most platforms announce it, and that is deliberate, because a silent departure means people keep addressing somebody who is not there. Muting is the quiet alternative and is what most people actually want.
The social problem with leaving is real and most platforms have decided that the confusion caused by silent departures is worse than the awkwardness of an announcement.
Muting gets you the outcome without the announcement: the conversation stops notifying you, and you read it when you choose to. In most busy groups that is the actual complaint.
On Naven, muting a conversation stops it notifying you while leaving you in it.
