REVEAL NEXT/TOGGLE ON ANKI REMOTE FOR IPAD (IOS)

I have been trying to figure out how to add the 'Reveal Next' button to my 8bitDo2 Anki remote to use on my AnkiMobile (iPad). I have this button configured on my laptop Anki, but I cannot figure out how to add it for the iPad. I use Anki on the treadmill and this would be great if it could work. I have attempted to add the 'User Action 1' but it doesn't work. Please help!
