The "Continue on one of your devices" message is likely part of the implementation of the Passkey feature for iOS, iPad 16 and Ventura. It is currently only supported by certain web sites and apps, including the Safari app. The site or app is making a call to your trusted device(s) for you to authenticate from the device itself (using Face ID or Touch ID). Tap Settings, then your name at the top and it should prompt you for Face ID or Touch ID, then approve the action on the other device.
