method Deno.Permissions.prototype.query
Permissions.prototype.query(desc: PermissionDescriptor): Promise<PermissionStatus>
Resolves to the current status of a permission.
Note, if the permission is already granted, `request()` will not prompt
the user again, therefore `query()` is only necessary if you are going
to react differently existing permissions without wanting to modify them
or prompt the user to modify them.
```ts
const status = await Deno.permissions.query({ name: "read", path: "/etc" });
console.log(status.state);
```
desc: PermissionDescriptor
Promise<PermissionStatus>
