So can anyone comment on exactly what "Rich Hints Agent" is, and why it suddenly needed additional permissions? And why is the ability to act on this "Extension upgrade requires additional permissions..." user prompt see the offending extension bizarrely hidden from user interaction to address it? Or why you can't disable the extension, or deselect "Allow access to search page results"?
As was mentioned by another user, searching for information on "Rich Hints Agent" comes up with nothing. Not exactly comfortable to learn that there are several hidden extensions operating in the background, with no transparency on their purpose, or what data they are sharing without my explicit consent.
Hopefully a Dev will see this thread and provide some clarity.
