Im trying to close a websocket from an npm package that connects to a third party service.

I instantiate the ws by doing:

ws = BitMexPlus({
            apiKeyID:     rows[i].bot_key.apiKeyID,
            apiKeySecret: rows[i].bot_key.apiKeySecret
})

This then calls another np package within it and makes the connection to the 3rd party.

How ever I want to be able to close the ws at will so naturally I do:

ws.close()

but I get the error:

ws.close is not a function

how ever for error handling and proper logging I do:

ws.on('end', async (code) => {console.log(code)})

and this works flawlessly.

Keep in mind the code dealing with this error handling is buried all the way inside the second package. So technically I should be able to close it with the ws instantiation.

How should I be calling the endpoint to close it?
