laravel - 如何在政策中允许新星资源行动

Nova 2.0 Laravel 5.8

我有一个nova资源Document（包含文件url，相关外键和title），我已经policy使用create和定义了它，并且updatefalse设置为true，所有其他资源都设置为true，因此PDF是从另一资源生成的，因此我不需要允许它创建或编辑的文件，现在一切正常，但是与action此文档资源上的另一个文件一样，我想下载这些文件，但出现错误“ Sorry you are not authorized to take this action”，因此，如何action启用它Policy。

DocumentPolicy类
