我有两个模型：User和Role。它们具有多对多关系，其中RoleUser充当透视表。
这是我的RoleUser模型：

<?php
 
namespace App\Models;
 
use Illuminate\Database\Eloquent\Model;
use Illuminate\Database\Eloquent\Relations\BelongsToMany;
 
class Role extends Model
{
    /**
     * The users that belong to the role.
     */
    public function users(): BelongsToMany
    {
        return $this->belongsToMany(User::class)->using(RoleUser::class);
    }
}

我如何获取使用latestOfMany的最新用户？比如，

return $this->hasOne(User::class)->using(RoleUser::class)->latestOfMany();
