Got the Citi PremierMiles credit card for the AirPods Pro signup bonus, but don't really have much use for the card itself. If I cancel the card now, will I be charged the annual fee?

I've already received the AirPods, and have used the card literally zero times. Are there any implications if I cancel the card simply because I have no use for it? I don't remember the T&Cs stating that I'll be charged anything, but just wanted to check with the community before doing anything.
