[Question] How to check/verify that Aurora Store APKs are exactly the same as Google Play Store APKs?

Hi, sorry to bother, is there any way to do this?

Some proprietary banking apps that I have to use are only available through Google Play Store so I’m thinking on install them (or better Aurora Store itself?) inside Shelter app, but need to verify that APKs have not been tampered with, how can I check this?, is it possible?

Thanks a lot in advance everybody and hope you all had/have a beautiful year’s end/beginning!
