traded in my iphone, airpod pros (2nd gen) say they're not mine now that they’re connected to new phone

i recently traded in my iphone 11 for the iphone 15. i did a factory reset on my iphone 11 and gave it to my local provider’s store. i connected my airpod pros (2nd generation) that i bought NEW from target to my new iphone 15 and i keep getting notifications that the owner of the airpods can see my location. i am and always have been the only owner of these airpods. i already factory reset my old iphone, turned it in, so i have no way to remove it from my old phone’s “find my”. i’m not really sure what to do bc i keep getting notifications about the “owner”, WHICH IS ME, being able to see my location and my airpods keep making noise as if they’re lost. what do i do about this??
