That's the difference, do not use any crypto wallet app that faliled to give it's users their private keys or recovery seed, it's same sad news with coinbase wallet, stay away or risk losing all your digital currency, such wallets with no private keys are just online wallets
True, the risk is very big even though there are also small benefits in it, but if a wallet like that I think there will be more risk when used because there is no recovery seed or private key that we can store safely.
