Other Set guest cookie expiration

[Mr. Jinx]

Would it be easily possible to set the expiration of XF guest cookies to be longer than the current session?
They are currently session based.

If a guest dismisses a notice, or the cookie warning, it will come back once the guest closes and reopens the browser.
I would like to set an expiry time for this, like 90 days.

So, anyone on this helpful forum willing to help us with this?
It should be possible, but I have no clue where to look for. Already searched the templates but could not find anything about session cookies.

Nobody willing to help? A few suggestions where to look in the code would be helpful.

ps: Thanks for all the PM offers but I am not looking for yet another paid add-on, this is just basic stuff that probably needs a few lines changed.
