Y para comunicarte usando WebSockets con tu backend probablemente usarías las utilidades de tu frontend.

O podrías tener una aplicación móvil nativa que se comunica con tu backend de WebSocket directamente, en código nativo.

O podrías tener alguna otra forma de comunicarte con el endpoint de WebSocket.
