How do you get the current tenant id?

<?php

namespace App\Listeners;

use Filament\Events\TenantSet;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Support\Facades\Log;

class UpdateLatestTeamId
{
    /**
     * Create the event listener.
     */
    public function __construct()
    {
        //
        Log::info('UpdateLatestTeamId::__construct()');
    }

    /**
     * Handle the event.
     */
    public function handle(TenantSet $event): void
    {
        // get the user from the event
        $user = $event->getUser();

        // get the tenant (team) from the event
        $team = $event->getTenant();

        // update the user's latest_team_id
        $user->latest_team_id = $team->id;
        $user->save();
    }
}

    protected $listen = [
        Registered::class => [
            SendEmailVerificationNotification::class,
        ],
        'Filament\Events\TenantSet' => [
            'App\Listeners\UpdateLatestTeamId',
        ],
    ];
