Here's a helpful article from Google about linking:
Send a link to a shared file
If you’ve set a file or folder to "Anyone with the link" or "Public," you can send the link to another person and they’ll be able to access it.
- Go to drive.google.com.
- Check the box next to the file or folder you'd like to share.
Click the Share icon .
- Copy the link at the top of the sharing settings.
- Send the link to another person or mailing list in an email or chat.
