Just want to know there have any time out function in ServiceDesk Plus?

For example, some one log in ServiceDesk Plus by web, and haven't any action after a period of time (15 min), is there will have any message pop out which say you will be log out after 5 mins??

Or the window will auto log out after 30 mins??

Anyone can advise and billion thanks if someone can reply my question

Thanks and regards,
