I've never used Gemini computer use, but I assume it's the same:

Claude computer use takes control of your whole computer inputs (mouse and keyboard) plus screenshots. You just log in, tell Claude you're logged in, and let it get to work. It'll use the browser you're logged in with.

The chrome extension is a little better because it only takes control of its own chrome tabs (again: you just log in.)
