Some websites (like Facebook) use a bespoke URL structure specifically for sharing. For example, I’ve received URLs that look like this: https://www.facebook.com/share/r/asdfgkfkshf

The only way to remove the tracking from that is to put it into one of those redirect checker sites to see where it leads (you’ll still have to remove additional URL parameters after you find out where it redirects to)

Facebook will just know that your friend generated a share URL, and then someone accessed it via the redirect checking site.
