Libraries available for SocketIO

I want to connect to a SocketIO server. A simple Google search shows two libraries:

  1. socket.io-client-ocaml which was last updated 6 years ago,
  2. ocaml-socketio which was last updated 11 years ago.

Looks like neither of the above libraries are maintained anymore. From my limited understanding SocketIO uses websockets as a base and build upon it, thus I can’t use the package ocaml-websockets directly. Is this correct?

Is there any currently maintained OCaml library for SocketIO?
