I don't have access to my pixelbook right now, I should in a couple of weeks! Once I do I will get you the logs.
ChromeOS uses Debian 11 in a container, it allows you to run Linux apps along side android apps and the Chrome Web browser. It's actually pretty slick and gives a lot of flexibility.
I don't know for sure, but am assuming the issue is chromeos not allowing an app from the container to control the mouse & keyboard.
