How to send the command to ask for Twitch capabilities COMMANDS, MEMBERSHIP, TAGS

Is there a function accessible in Client that will send the message to request the capabilities?

https://dev.twitch.tv/docs/irc/capabilities/

[AlcaDesign]

tmi.js does this automatically.

tmi.js/lib/client.js

Lines 1189 to 1193 in e4547c0

	let caps = 'twitch.tv/tags twitch.tv/commands';
	if(!this._skipMembership) {
	caps += ' twitch.tv/membership';
	}
	this.ws.send('CAP REQ :' + caps);

Ok, then should the JOIN and PART messages be visible in the message handler?

    self.client.on('message', function (target, context, msg, isSelf) {
    //JOIN or PART here?
    });

[AlcaDesign]

client.on('join', (channel, username, isSelf) => {
    if(isSelf) {
        console.log(`[Self] Joined ${channel}`);
    }
    else {
        console.log(`[${channel}] ${username} joined`);
    }
});
client.on('part', (channel, username, isSelf) => {
    if(isSelf) {
        console.log(`[Self] Parted ${channel}`);
    }
    else {
        console.log(`[${channel}] ${username} parted`);
    }
});

Oh they throw their own events. Where is the documentation for that?
