how to make relation between multiple models (users, shops and roles)

Hi,

I have 3 tables users, shops and roles, each user can create multiple shops and each shop can be managed by multiple users with 2 roles owner(shop creator) and admin.

when a user create a new shop owner role will be assigned and also the same user could be an admin in other shops,

Tables

//Users table:

        $table->increments('id');
            $table->string('name');
            $table->string('email')->unique()->index();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();   

//Shops table:

            $table->increments('id');
            $table->integer('shop_type_id')->unsigned()->index();
            $table->string('name');
            $table->string('image');
            $table->text('description');
            $table->timestamps();

//Roles table:
            
           $table->increments('id');
           $table->string('name');

//Role shop table:
       
            $table->integer('role_id')->unsigned()->index();
            $table->integer('shop_id')->unsigned()->index();
            $table->integer('user_id')->unsigned()->index();

Models:

//User model:

class User extends Authenticatable
{
    public function shop()
        {
            return $this->hasMany(Shop::class);
        }

}
//Role model:

class Role extends Model
{
    public $timestamps = false;

    public function users()
    {
        return $this->hasMany(User::class);
    }

    public function shops()
    {
        return $this->belongsToMany(Shop::class);
    }
}

//Shop

class Shop extends Model
{
  public function user()
    {
        return $this->belongsTo(User::class);
    }

    public function roles()
    {
        return $this->belongsToMany(Role::class);
    }
}
