Tech help: how do I copy magnet link info (new iPhone)?

Hi. I never had a problem accessing and copying the magnet link on my iPhone 6s, but on my “new” iPhone
8 it’s all different. Just holding the link doesn’t get me the right menu to copy the data. What am I doing
wrong? I’d google this if I even knew what to call it, but I’ve never even seen this kind of link anywhere
other than sites like these. Thanks for your help.
