 Deferring a message will allow you to respond for up to 15 mins, but you'll have to defer within three seconds.
-When you defer the user will see a "this bot is thinking" message until you send a message, This message can be ephermical (hidden) or visible.

+When you defer the user will see a "this bot is thinking" message until you send a message, This message can be ephemeral (hidden) or visible.
+``.defer`` has a ``hidden`` parameter, which will make the deferred message ephemeral.
 
 We suggest deferring if you might take more than three seconds to respond, but if you will call ``.send`` before three seconds then don't.
