Hi there, unfortunately that was a feature that was built into the manufacturer's OS, it's not a stock Android option. And for some reason, that was removed from newer Samsung devices (older ones did have access to cloud services like Photos).
Now, in order to see the pictures in your cloud, you have to use the Photos app or a 3rd party app that allows access to Photos. You can also 'link' your Photos and Drive accounts so that a Photos folder appears automatically in Drive and then see those images through the phone's file manager or a 3rd party app that allows cloud storage connections to Drive (way more common than connection to Photos).
