If clicked on in a game, I believe a link will open to an in-game compendium handout. I just tested with a draft horse: paste this into chat and click on it: <a href="https://roll20.net/compendium/dnd5e/Monsters:Draft%20Horse#h-Draft%20Horse" rel="nofollow">https://roll20.net/compendium/dnd5e/Monsters:Draft%20Horse#h-Draft%20Horse</a> If putting into handout text, just make it an ordinary hyperlink.
