ActionResponse::download with a path instead of an url?

[m-lotze]

Is there any reason, why ActionResponse::download only accepts an url and therefore only publicly available files?

I think it should also work with a path to a file.

Because Action are executed using XHR as default and the download link get triggered by the front-end to start the download.

You should be able to use Storage temporary URL.
