[question] Difficulties using with typescript

[DrakoPOD]

I have this code, that works perfectly in vanilla JS:

aedes.on('publish', function (packet, client) {
	//More code...
	aedes.publish({
		topic: 'auth/' + client.id,
		payload: '1',
		qos: 0
	});
});

But with typescript it says that is missing one argument, in that case is callback, Then, I put the callback, but get another error that says (translate from Spanish):

Cannot assign an arg of type "{ topic: string; payload: string; qos: 0; }" to param of type "PublishPacket".
to type "{ topic: string; payload: string; qos: 0; }" is missing the following properties of type "IPublishPacket": cmd, dup, retain

It suppose that these properties should be defaults or optional, also the docs doesn't offer explanation of what properties have or what is PublishPacket. I know that properties are standard of mqtt, but at least a external link or something.

Also, I got another error with aedes.authenticate
'authenticate' does not exist on type 'aedes'

The code can run, at least I don't use typescript. Adding // @ts-expect-error ignore the problem. But, how I can import the type definitions?

@DrakoPOD you can add the authenticate function in aedes options

Yeah them are not mandatory, I think types could be improved here. Would you like to submit a PR to fix them?
