Implementing Websocket Client Functionality in Elixir

ArjaSpellan is facing a challenge with implementing websocket clients in Elixir applications. They've encountered a couple of projects such as 'websockex', which appears to be no longer maintained, and 'mint_web_socket', which requires users to handle GenServer wrapping by themselves. ArjaSpellan is in search of the best practice or commonly adopted approach for setting up websocket clients, especially considering the need for their application to operate as a client that communicates with another application using JSON-RPC via websockets.
