Desktop/browser notification on new Tickets

i am trying to figure out how to setup the system so i can get a browser notification each time a new ticket is created in our system. (ie status is open & ticket owner is empty).

i see these two threads

https://help.zoho.com/portal/en/community/topic/one-hour-notification-for-new-tickets

---this one i dont see the options about time based stuff ie hours since created.

i see this concept mentioned here but not sure how to implement it.

Thanks
