The link would have been saved to the clipboard. Phones can vary on how those are treated. Some may only store one item at a time, which is erased whenever the next copy command, link creation, etc. is used. Other phones will have a more advanced clipboard that retains multiple items and allow direct access to it. I'm not familiar with your specific device, but one way to check is to open a text entry box or note app and long press the in the text entry area. If there is a paste option, try it and see what it pastes. If you see a clipboard option, select that and see what all is in it.
In any case, those clips are only stored temporarily and will be erased as new clips are added.
