I tend to add

    /**
     * The event's broadcast name.
     *
     * @return string
     */
    public function broadcastAs()
    {
        return 'chat';
    }

I do this since the Laravel docs

Echo.private(`orders.${orderId}`)
    .listen('OrderShipmentStatusUpdated', (e) => {
        console.log(e.order);
    });

But in the Pusher UI you can see it comes in as a full namesapce `\\App\\Events\\OrderShipmentStatusUpdated'

Echo in the Vue.js files then looks like this

        Echo.channel(`editor.${this.$page.props.user.id}`)
            .listen('.editor', (e) => {

            })
            .listen('.cliche', (e) => {
                this.cliches_report = e.report.found;
            })
            .listen('.passive', (e) => {
                this.passive_report = e.report.found;
            })

Adding a "." in from of the listen.
