Am i misunderstanding relation managers?

Hi all, I keep getting the below error

Call to undefined method App\Models\Product::categories()

Call to undefined method App\Models\Product::categories()

When trying to attach a product to my category through my CategoryResource relation manager. Can anyone give me advise I can't see where i'm going wrong - sorry for the inconvenience.

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    protected $fillable = [
        'sku',
        'description',
        'category_id',
        'created_at',
        'updated_at'
    ];

    public function category()
    {
        return $this->belongsTo(Category::class);
    }

}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Product extends Model
{
    use HasFactory;

    protected $fillable = [
        'sku',
        'description',
        'category_id',
        'created_at',
        'updated_at'
    ];

    public function category()
    {
        return $this->belongsTo(Category::class);
    }

}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;

    protected $fillable = [
        'name',
        'created_at',
        'updated_at'
    ];

    public function products()
    {
        return $this->hasMany(Product::class); 
    }
}

<?php

namespace App\Models;

use Illuminate\Database\Eloquent\Factories\HasFactory;
use Illuminate\Database\Eloquent\Model;

class Category extends Model
{
    use HasFactory;

    protected $fillable = [
        'name',
        'created_at',
        'updated_at'
    ];

    public function products()
    {
        return $this->hasMany(Product::class); 
    }
}

Give this page a thorough read. With a belongsTo you need to use an AssociateAction. https://filamentphp.com/docs/3.x/panels/resources/relation-managers
