When we want to make a user subscribed features then we can use presence channels rather than private channels. This makes it easy to build powerful, collaborative application features such as notifying users when another user is viewing the same page.

Keep in mind that all presence channels are also private channels. Therefore, users must be authorized to access them. By the way, when defining authorization callbacks for presence channels, you will not return true if the user is authorized to join the channel. Instead, you should return an array of data about the user. See the below code to understand: 

Broadcast::channel('chat.{roomId}', function ($user, $roomId) {
    if ($user->canJoinRoom($roomId)) {
        return ['id' => $user->id, 'name' => $user->name];

To join a presence channel, you may use Echo's join method. The join method will return a PresenceChannel implementation which, along with exposing the listen method, allows you to subscribe to the herejoining, and leaving events.

    .here((users) => {
    .joining((user) => {
    .leaving((user) => {


Remember the joining method will be executed when a new user joins a channel, while the leaving method will be executed when a user leaves the channel. Hope it can help you.
