Your Chromebook is up to date
Version 128.0.6613.163 (Official Build) (64-bit)

That is up two numbers from my last update of
Version 128.0.6613.161.

This is the fifth new Chromebook I have had.
The other four went EOL as they fell apart.

I rarely ever see a Chromebook Update show up on its own. I usually Check For Updates before they do. And I do it by clicking the gear, and going to About ChromeOS and then clicking Check For Updates.
Never see them when I click the three dots.
