I’m building a app that make request to the leetcode graphql api. Inside this function header I’ve use the user stored cookie from my backend. My concern is how long does the cookie last, and how long do I need to re-update the cookie session?

We’ve recently (this week) noticed a new cookie on our site called __google_un. It hasn’t shown up before and I can’t find any information online about what it is or what it does.
