"Approve this iPhone." I log into iCloud to approve the phone on my iMac, but there is no prompt on the computer to approve the iPhone.

I forgot my password and entered the wrong password too many time and i was locked out of my iPhone. Tried for days to remember, no luck. I went to apple store and ended up buying a new phone because I basically had bricked the phone. After buying the new phone, I didn't sign into iCloud in case I remembered the password. After a few days, I found my password and went back to Apple with both phones. They switched me back to my original phone. Everything was ok, I just needed to verify with my other device to "Approve this iPhone". When I get home, I get on my iMac, but there is no message to "Approve this iPhone" anywhere. I am logged into iCloud on both devices. Where is the message to approve the phone on the computer?
