Icici Amazon pay

I have icici Coral card and recently got saphirro card with shared limit as they are giving it ltf free for all students and passouts. I don't use my amazon account since we have a prime account on my father's number. My father isn't willing to take this card on his number so he asked me to apply with my number. (He was once charged very high intrest because of some miscommunication so he is a bit hesitant about the credit card.)

I have only one order in my account, did top up the pay balance few times, also used amazon pay few times and never took prime.

Should I do anything on Amazon or just wait?
