Is there an NSOpenPanel alternative or can the panel be styled differently in SwiftUI?

I have asked a similar question here and at even at the Apple Developer's Forum. It seems like either I have the questions wrong or no one can / want's to comment on this subject.

The problem

I want to grant access to a folder outside the sandbox of my application. I know I can do this with an NSOpenPanel dialog - a modal popping up, where the folder is pre-selected, thus an empty view and the user is supposed to press an OK button.

The question

Since I find this "empty folder view with a random OK button" not really user friendly, I was wondering if there is a possibility to either

• use an NSOpenPanel alternative or
• adjust the styling of the panel

so that I simply have a modal popping up which alerts the user that the app needs access to a folder (which will be printed out in the alert window), with an OK and a Cancel button. I don't want to show locations on the system, an empty box of a folder and all the other stuff which is presented.

To clarify, this is what I have:

and this is what I want (or something similar):

I would really appreciate if someone could tell me if this is possible or not. At least point me to some reference (I could not find anything so far).

Thanks!

No. Not possible.

NSOpenPanel & NSSavePanel have a special relationship for sandboxed apps. They are sort of an app called PowerBox within your app that allow the user to pick a file or folder and return a security scoped URL to your code.

They are described in the documentation here

As such if you can’t do it using the NSSavePanel/NSOpenPanel API then it can’t be done.
