Can't find the autopay option

I am using the gold amex credit card and I set up autopay when I got it. I also have a chequing account with scotia that I use for all the payments towards my credit card. But I cannot find the autopay option either on the app or website. I needed to stop autopay for a while as I won't have enough money on the chequing account and I don't wanna get charged an overdraft fee. Any advice?
