Finding previously downloaded App Store apps on iPhone
I got a new used I phone. I want to reinstall some previous apps I’ve downloaded from AppStore but I can’t seem to find anything about previous downloaded apps
iPhone 6s Plus, iOS 15
You will find the list here:

Of course you would need to be using the same Apple Account used previously and hopefully the device had been properly wiped before you acquired the phone.
