Back camera is cracked can you repair it the trade in?

15 pro max, the zoom lens is smashed i’ve chipped away the excess glass the lens may have dust in it but weirdly, after removing the left over glass that was definetly covered in dust it fixed any distortion problems or “foggyness”

Recently thank god, apple care one came out and i was able to add my phone to it if i were to get the camera replaced, can it be turned down a repair under apple care one? if it’s fixed can i then trade it in for a new phone in store that same day OR will they give me a replacement unit if there’s dust in the camera and is trade in available for it
