Question

Answer 1

I think "Publish" is what is you need. The file can still be "Private".

Publish and embed Google Docs, Sheets, Slides & Forms To make a document, spreadsheet, or presentation, available for a large audience to see, publish a file. After you publish your file, you’ll have a URL that you can send to anyone or embed into your website.
