How do you copy&paste a user handle? - sh.itjust.works

There is (as far as I know) no easy way to copy a user handle to mention them in a post or comment. There isn’t a UI element or menu option on a post to do this. I can go to their just page and use the share button, but then I get (for example): https://lemmy.guide/link?target=@[email protected] [https://lemmy.guide/link?target=@[email protected]] That’s not Zach’s instance, it’s mine. To get the user handle I’d have to edit out the URL part, and change to the correct instance @[email protected]. Is that how it’s supposed to work? Is the instance change thing a bug? Is there a better way I don’t know about?
