在使用消息总线进行测试时，我发现每次收到聊天消息时，都会伴随一个 /chat/new-channel 通知。即使双方都已打开聊天窗口，也会出现这种情况。
[{"global_id":61583779,"message_id":134,"channel":"/chat/4","data":{"chat_message":{"id":6,"message":"nice to see you too","cooked":"<p>nice to see you too</p>","created_at":"2023-05-24T14:07:02.800Z","excerpt":"nice to see you too","available_flags":[],"thread_title":null,"chat_channel_id":4,"user":{"id":152,"username":"testuser","name":"testuser","avatar_template":"https://avatars.discourse-cdn.com/v4/letter/t/e495f1/{size}.png","moderator":false,"admin":false,"staff":false,"new_user":false,"primary_group_name":null,"assign_icon":"user-plus","assign_path":"/u/testuser/activity/assigned"},"chat_webhook_event":null,"uploads":[]},"type":"sent","staged_id":"66122c8d-ad8e-4754-b04a-e0ff75c4e898","staged_thread_id":null}}]

然后当发送另一条消息时
[{"global_id":61583803,"message_id":135,"channel":"/chat/4","data":{"chat_message":{"id":7,"message":"and another message","cooked":"<p>and another message</p>","created_at":"2023-05-24T14:08:01.128Z","excerpt":"and another message","available_flags":[],"thread_title":null,"chat_channel_id":4,"user":{"id":152,"username":"testuser","name":"testuser","avatar_template":"https://avatars.discourse-cdn.com/v4/letter/t/e495f1/{size}.png","moderator":false,"admin":false,"staff":false,"new_user":false,"primary_group_name":null,"assign_icon":"user-plus","assign_path":"/u/testuser/activity/assigned"},"chat_webhook_event":null,"uploads":[]},"type":"sent","staged_id":"67a062f9-28de-42c8-a037-c3d272584c3d","staged_thread_id":null}}]

source 似乎暗示每次创建消息时都会发送一个 new-channel 事件。
当然，如果是我对事物运作方式的理解完全错误，请随意嘲笑我，然后将此移至 Support 
这在我需要检查以允许侧边栏频道数量更严格的列表中，所以又少了一件事
