iPhone 8 Plus, iOS 16
Your tagline says you’re already running iOS 16.
If accurate you’re probably already “current” as iOS 16.7.10 is the most current OS for an “8.”
If you need an OS newer than 16; you’ll also need a newer iPhone on which to run it.
See how to update to the latest OS which your phone is capable of running here:
