How to use childprocess.send and process.on("message")?

main

const child = fork('xxx')
child.send("hi")

child

process.on("message', () => {})

fork has a binding:

rescript-nodejs/src/ChildProcess.res

Lines 129 to 130 in 2f93700

	@module("node:child_process") @val
	external fork: (string, array<string>) => t = "fork"

But I can't find one for send. Likewise there are a few on bindings, but nothing for on("message").

rescript-nodejs/src/ChildProcess.res

Lines 9 to 18 in 2f93700

	@send
	external onData: (t, @as("data") _, @uncurry (Buffer.t => unit)) => t = "on"
	@send
	external onDisconnect: (t, @as("disconnect") _, @uncurry unit => unit) => t = "on"
	@send
	external onError: (t, @as("error") _, @uncurry (Js.Exn.t => unit)) => t = "on"
	@send
	external onExit: (t, @as("exit") _, @uncurry int => unit) => t = "on"
	@send
	external onClose: (t, @as("close") _, @uncurry int => unit) => t = "on"

So both need to be added.
