When you click an emote on the chat it shows you information about that emote, if it is a global emote or what channel is that emote from. And when you click an username in the chat it shows information about that user, like when you write /user <username>.
So if we have a command that makes the same that when you click the username. It would be nice to have a command that makes the same that when you click an Emote, that way if you know the code of that emote but you don't have it, you don't have to wait until someone else send that emote to click it and look information about that emote.
