Thanks for teaching me! And for the link for more info!
Anything after the “?” is a parameter, and not part of the page URL itself.
In *most* cases this is unnecessary junk you can remove, in *some* cases it forms part of the request you might need to keep. It’s easy to experiment by just trying it in your browser URL bar. Some parameters have obvious names and purpose, most will not.
For example:
Twitter: s, t - both unnecessary trackers
Facebook: fbclid- unnecessary tracker
YouTube: v, t - these are the actual ids of the video with an optional timestamp, both potentially relevant for you

Sometimes, if I’m not sure, I will keep removing parts of the url and testing it in the browser until it doesn’t work. Then I add that part back and use the link that way.
