First shotgun. Cleaning kit/supplies question

Hi! I’ve owned and fired plenty of pistols over the years but I just bought my first shotgun. Mossberg 500 persuader 20 ga. with a 20.75” barrel. I like putting together my own box of cleaning supplies for my handguns and would like advice on what all I’d need to do the same for a shotgun should different gear be advised or necessary. Thank you in advance.
