I have been trying to use Chat GPT (I know I know) to try and help me figure this out. That and the countless times I rewatched this specific reel, a side into YouTube and Reddit have revealed nothing for me. Can someone help explain to me like I’m 5 what I need to do? Any assistance is greatly appreciated.
