"SQLSTATE[42S02]: Base table or view not found: 1146 Table 'db_paktikum_prognet.notifications' doesn't exist (SQL: select * from `notifications` where `notificat ▶"

I already define model and make $protected table = 'my table name' but it doenst work

and here is my model code

    <?php

namespace App;

use Illuminate\Database\Eloquent\Model;
use Illuminate\Notifications\DatabaseNotification;
class admin_notification extends Model
{
    protected $table = 'admin_notifications';
}

I expected to use my table name for notification
