Method Illuminate\Auth\SessionGuard::karyawan does not exist - Laravel 8 - laravel

Question

I'm having a problem with my Auth. So, I'm doing login but not using User models. I made my own models called Karyawan.
The error is:
Method Illuminate\Auth\SessionGuard::karyawan does not exist.
This is the public function on my controller:
public function admin()
{
return view('admin', [
"title" => "Admin",
"karyawan" => Karyawan::all()
]);
}
This is the auth.php
return [
'defaults' => [
'guard' => 'web',
'passwords' => 'users',
],
'guards' => [
'web' => [
'driver' => 'session',
'provider' => 'users',
],
],
'providers' => [
'users' => [
'driver' => 'eloquent',
'model' => App\Models\Karyawan::class,
],
],
'passwords' => [
'users' => [
'provider' => 'users',
'table' => 'password_resets',
'expire' => 60,
'throttle' => 60,
],
],
my Karyawan models:
namespace App\Models;
use App\Models\Cuti;
use App\Models\Role;
use App\Models\Divisi;
use App\Models\Jabatan;
use App\Models\User;
use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Foundation\Auth\User as Authenticatable;
class Karyawan extends Authenticatable
{
use HasFactory;
protected $guarded = ['karyawan_id'];
protected $table = 'karyawans';
public function scopeSearch($query, array $searchs) {
$query->when($searchs['search'] ?? false, function($query, $search) {
return $query->where('nama', 'like', '%' . $search . '%')
->orWhere('divisi_id', 'like', '%' . $search . '%')
->orWhere('jabatan_id', 'like', '%' . $search . '%')
->orWhere('agama', 'like', '%' . $search . '%')
->orWhere('nik', 'like', '%' . $search . '%');
});
}
public function role_id()
{
return $this->belongsTo(Role::class);
}
public function divisi()
{
return $this->belongsTo(Divisi::class);
}
public function jabatan()
{
return $this->belongsTo(Jabatan::class);
}
public function cuti()
{
return $this->hasMany(Cuti::class);
}
}
and this is the view I want to display:
<div class="dropdown">
<a href="#" class="d-flex align-items-center link-dark text-decoration-none dropdown-toggle" id="dropdownUser2" data-bs-toggle="dropdown" aria-expanded="false">
<img src="/images/avatar/avatar-2.png" alt="" width="32" height="40" class="rounded-circle me-2">
<strong>{{ auth()->karyawan()->nama }}</strong>
</a>
<ul class="dropdown-menu text-small shadow" aria-labelledby="dropdownUser2">
<li>
<form action="">
<button type="submit" class="dropdown-item">Logout</button>
</li>
</ul>
</div>
<main class="col-md-9 ms-sm-auto col-lg-10 px-md-4">
<div class="d-flex justify-content-between flex-wrap flex-md-nowrap align-items-center pt-3 pb-2 mb-3 border-bottom">
<h1 class="h2" style="position:absolute margin: auto auto"><p></p>Profil Pengguna</h1>
</div>
<center>
<img src="/images/avatar/avatar-2.png" style="width: 200px">
<p><h1>Selamat Datang, {{ auth()->karyawan()->nama }}</h1> </p>
<p> Divisi: {{ auth()->divisi()->nama_divisi }}</p>
<p> Jabatan: {{ auth()->jabatan()->nama_jabatan }}</p>
<p> Role: {{ auth()->role()->nama_role }}</p>
<p> Sisa cuti Anda: {{ auth()->karyawan()->sisa_cuti }}</p>
</center>
</div>
</main>
PS: The login auth is successful, not failed. the only problem is it can't display who is the user doing the login.
